Esophageal Perforation Successfully Treated With Evt, Kavea Panneerselvam, Ronald Samuel, Robert J Sealock

Faculty, Staff and Students Publications

Esophageal perforation is rare and carries high morbidity and mortality. A high degree of suspicion is needed for timely diagnosis and treatment. A 54-year-old man presented with fever and confusion. Imaging revealed air in the hepatic inferior vena cava and concern for a fistula between the distal esophagus and the inferior vena cava. An upper endoscopic evaluation revealed a dental floss pick penetrating the distal esophagus. The foreign body was removed, and endoluminal vacuum therapy was used to close the perforation. Endoluminal vacuum therapy is an emerging therapy to treat full-thickness gastrointestinal injuries.

Acute malnutrition, or wasting, is implicated in over half of all deaths in children under five and increases risk of infectious disease. Studies in humans and preclinical models have demonstrated that malnutrition is linked to an immature intestinal microbiota characterized by increased prevalence of Enterobacteriaceae. Observational studies in children with moderate acute malnutrition (MAM) have also observed heightened systemic inflammation and increased circulating bacterial lipopolysaccharides (LPS; endotoxin). However, the mechanisms that underpin the systemic inflammatory state and endotoxemia, and their pathophysiological consequences, remain uncertain. Understanding these pathophysiological mechanisms is necessary to design targeted treatments that will improve the unacceptable rate …

Effect Of 3 Days Of Oral Azithromycin On Young Children With Acute Diarrhea In Low-Resource Settings: A Randomized Clinical Trial, Antibiotics For Children With Diarrhea (Abcd) Study Group, Tahmeed Ahmed, Farah Naz Qamar, Mohammad Tahir Yousafzai, Shahida Qureshi, Sadia Shakoor, Rozina Thobani, Aneeta Hotwani, Furqan Kabir, Jan Mohammed

Department of Paediatrics and Child Health

Importance: World Health Organization (WHO) guidelines do not recommend routine antibiotic use for children with acute watery diarrhea. However, recent studies suggest that a significant proportion of such episodes have a bacterial cause and are associated with mortality and growth impairment, especially among children at high risk of diarrhea-associated mortality. Expanding antibiotic use among dehydrated or undernourished children may reduce diarrhea-associated mortality and improve growth.
Objective: To determine whether the addition of azithromycin to standard case management of acute nonbloody watery diarrhea for children aged 2 to 23 months who are dehydrated or undernourished could reduce mortality and improve linear …

INTRODUCTION: Functional luminal imaging probe (FLIP) panometry can evaluate esophageal motility in response to sustained esophageal distension at the time of sedated endoscopy. This study aimed to describe a classification of esophageal motility using FLIP panometry and evaluate it against high-resolution manometry (HRM) and Chicago Classification v4.0 (CCv4.0).

METHODS: Five hundred thirty-nine adult patients who completed FLIP and HRM with a conclusive CCv4.0 diagnosis were included in the primary analysis. Thirty-five asymptomatic volunteers ("controls") and 148 patients with an inconclusive CCv4.0 diagnosis or systemic sclerosis were also described. Esophagogastric junction (EGJ) opening and the contractile response (CR) to distension (i.e., …

Impact Of Compensated Cirrhosis On Survival In Patients With Acute-On-Chronic Liver Failure, Kessarin Thanapirom, Tongluk Teerasarntipan, Sombat Treeprasertsuk, Ashok Choudhury, Manoj K. Sahu, Rakhi Maiwall, Viniyendra Pamecha, Richard Moreau, Saeed Hamid, Amna Subhan Butt

Section of Gastroenterology

Background and aims: Acute-on-chronic liver failure (ACLF) is considered a main prognostic event in patients with chronic liver disease (CLD). We analyzed the 28-day and 90-day mortality in ACLF patients with or without underlying cirrhosis enrolled in the ACLF Research Consortium (AARC) database.
Methods: A total of 1,621 patients were prospectively enrolled and 637 (39.3%) of these patients had cirrhosis. Baseline characteristics, complications and mortality were compared between patients with and without cirrhosis.
Results: Alcohol consumption was more common in cirrhosis than non-cirrhosis (66.4% vs. 44.2%, p < 0.0001), while non-alcoholic fatty liver disease/cryptogenic CLD (10.9% vs 5.8%, p < 0.0001) and chronic HBV reactivation (18.8% vs 11.8%, p < 0.0001) were more common in non-cirrhosis. Only 0.8% of patients underwent liver transplantation. Overall, 28-day and 90-day mortality rates were 39.3% and 49.9%, respectively. Patients with cirrhosis had a greater chance of survival compared to those without cirrhosis both at 28-day (HR = 0.48; 95% CI 0.36-0.63, p < 0.0001) and 90-day (HR = 0.56; 95% CI 0.43-0.72, p < 0.0001), respectively. In alcohol CLD, non-cirrhosis patients had a higher 28-day (49.9% vs. 23.6%, p < 0.001) and 90-day (58.4% vs. 35.2%, p < 0.001) mortality rate than cirrhosis patients. ACLF patients with cirrhosis had longer mean survival than non-cirrhosis patients (25.5 vs. 18.8 days at 28-day and 65.2 vs. 41.2 days at 90-day). Exaggerated systemic inflammation might be the reason why non-cirrhosis patients had a poorer prognosis than those with cirrhosis after ACLF had occurred.
Conclusions: The 28-day and 90-day mortality rates of ACLF patients without cirrhosis were …

Vaccine uptake is a multifactor measure of successful immunization outcomes that includes access to healthcare and vaccine hesitancy for both healthcare workers and communities. The present coronavirus disease (COVID-19) pandemic has highlighted the need for novel strategies to expand vaccine coverage in underserved regions. Mobile clinics hold the promise of ameliorating such inequities, although there is a paucity of studies that validate environmental infection in such facilities. Here, we describe community-based management of COVID-19 through a Smart Pod mobile clinic deployed in an underserved community area in the United States (Aldine, Harris County, TX, USA). In particular, we validate infection …

Mapk6-Akt Signaling Promotes Tumor Growth And Resistance To Mtor Kinase Blockade, Qinbo Cai, Wolong Zhou, Wei Wang, Bingning Dong, Dong Han, Tao Shen, Chad J Creighton, David D Moore, Feng Yang

Faculty, Staff and Students Publications

Mitogen-activated protein kinase 6 (MAPK6) is an atypical MAPK. Its function in regulating cancer growth remains elusive. Here, we reported that MAPK6 directly activated AKT and induced oncogenic outcomes. MAPK6 interacted with AKT through its C34 region and the C-terminal tail and phosphorylated AKT at S473 independent of mTORC2, the major S473 kinase. mTOR kinase inhibitors have not made notable progress in the clinic. Our identified MAPK6-AKT axis may provide a major resistance pathway. Besides repressing growth, inhibiting MAPK6 sensitized cancer cells to mTOR kinase inhibitors. MAPK6 overexpression is associated with decreased overall survival and the survival of patients with …

Glycogen storage disease type Ia (GSDIa) is caused by defective glucose-6-phosphatase, a key enzyme in carbohydrate metabolism. Affected individuals cannot release glucose during fasting and accumulate excess glycogen and fat in the liver and kidney, putting them at risk of severe hypoglycaemia and secondary metabolic perturbations. Good glycaemic/metabolic control through strict dietary treatment and regular doses of uncooked cornstarch (UCCS) is essential for preventing hypoglycaemia and long-term complications. Dietary treatment has improved the prognosis for patients with GSDIa; however, the disease itself, its management and monitoring have significant physical, psychological and psychosocial burden on individuals and parents/caregivers. Hypoglycaemia risk persists …

Health And Economic Benefits Of Achieving Hepatitis C Virus Elimination In Pakistan: A Modelling Study And Economic Analysis, Aaron G. Lim, Nick Scott, Josephine G. Walker, Saeed Hamid, Margaret Hellard, Peter Vickerman

Section of Gastroenterology

Background: Modelling suggests that achieving the WHO incidence target for hepatitis C virus (HCV) elimination in Pakistan could cost US$3.87 billion over 2018 to 2030. However, the economic benefits from integrating services or improving productivity were not included.
Methods and findings: We adapt a HCV transmission model for Pakistan to estimate the impact, costs, and cost-effectiveness of achieving HCV elimination (reducing annual HCV incidence by 80% by 2030) with stand-alone service delivery, or partially integrating one-third of initial HCV testing into existing healthcare services. We estimate the net economic benefits by comparing the required investment in screening, treatment, and healthcare …

Role Of Gut Microbiome In Covid-19: An Insight Into Pathogenesis And Therapeutic Potential, Ikram Hussain, Gabriel Liu Yuan Cher, Muhammad Abbas Abid, Muhammad Bilal Abid

Department of Pathology and Laboratory Medicine

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in an unprecedented global crisis. Although primarily a respiratory illness, dysregulated immune responses may lead to multi-organ dysfunction. Prior data showed that the resident microbial communities of gastrointestinal and respiratory tracts act as modulators of local and systemic inflammatory activity (the gut-lung axis). Evolving evidence now signals an alteration in the gut microbiome, brought upon either by cytokines from the infected respiratory tract or from direct infection of the gut, or both. Dysbiosis leads to a "leaky gut". The intestinal permeability then allows access to …

A Rare Complication In A Covid-19 Positive Patient With Sigmoid Colon Cancer-Hemoperitoneum Due To Gallbladder Necrosis Following Micro-Thrombosis, Mihai Faur, Andrei Moisin, Calin Mohor, Dan Sabau

Journal of Mind and Medical Sciences

Covid-19, also known as acute respiratory syndrome 2019-nCoV, severe acute respiratory syndrome (SARS) 2, and Wuhan pneumonia, is a viral respiratory disease caused by a SARS-associated coronavirus (SARS-CoV-2). The most serious complications of Covid-19 are due to the development of micro-thrombosis in various organs and systems as a result of the high levels of pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin 1 and 6) which initiate the activation of coagulation and the generation of thrombin. Several studies demonstrated the poor outcome of Covid-19-infected patients who underwent surgery, suggesting that surgery may accelerate and exacerbate Covid-19 progression. We report the case …

Digestive tract malformations requiring surgical repair in association with esophageal atresia are rare occurrences. Because of this uncommon presentation of esophageal atresia, its evaluation and management are often difficult, requiring extensive workup and multiple surgical procedures. We present our experience with esophageal atresia associating gastrointestinal congenital anomalies in the last 10 years. Clinical and surgical perspectives were pointed willing to make relevant observations in matters of diagnosis and treatment strategy in these patients. Therefore, 7 cases resembling this pattern were identified – duodenal atresia and anorectal malformation being the most common coexistent malformations. All the cases exhibited technical and procedural …

The Impact Of Patient-Dependent Risk Factors On Morbidity And Mortality Following Gastric Surgery For Malignancies, Bogdan Dumitriu, Sebastian Valcea, Gabriel Andrei, Mircea Beuran

Journal of Mind and Medical Sciences

Gastric cancer remains a leading cause of mortality worldwide. The treatment for gastric cancer is multimodal, in which gastrectomy remains the only curative approach. However, gastric resection is often associated with increased morbidity and mortality rates, depending on several factors. These factors can be attributed to the patient as comorbidities or effects of the disease upon him and, on the other hand, there are risk factors independent of the patient, such as aspects of the tumor (type, staging, location), experience of the surgical and anesthetic team, logistics of the hospital, yield of adjuvant therapies etc. We recognize the fact that …

The gastrointestinal microbiome contains at least 100 trillion microorganisms (bacteria, viruses, fungi), whose distribution varies from the mouth to the rectum spatially and temporally throughout one's lifetime. The microbiome benefits from advancing research due to its major role in human health. Studies indicate that its functions are immunity, metabolic processes and mucosal barrier. The disturbances of these functions, dysbiosis, influence physiology, lead to diabetes, inflammatory bowel disease, obesity and colon tumorigenesis. The third most common form of cancer, colorectal cancer, is the result of many factors and genes, and although the link between dysbiosis and this type of cancer is …

How Opportune Is Multigene Testing In Metastatic Colorectal Cancer? A Review, Cristina Orlov-Slavu, Andreea Parosanu, Mihaela Olaru, Dragos Serban, Ioana Paunica, Cornelia Nitipir

Journal of Mind and Medical Sciences

Personalized treatment in oncology is the most innovative method of care. The best method to establish personalized treatment is by genetic characterization of the malignant cell.

Theoretically, the more detailed the characterization, the more effective the choice of treatment becomes. Currently, there are fast and relatively low-cost options that allow such genetic characterization. However, test results sometimes do not detect targetable alterations and, even if they do detect, the use of the treatment-alteration combination does not always generate a satisfactory oncological response.

The present paper aims to answer two questions. First, how targetable can the most common gene alterations in …

The use of human tissue stem cell-derived organoids has advanced our knowledge of human physiological and pathophysiological processes that are unable to be studied using other model systems. Increased understanding of human epithelial tissues including intestine, stomach, liver, pancreas, lung, and brain have been achieved using organoids. However, it is not yet clear whether these cultures recapitulate in vivo organ-to-organ signaling or communication. In this work, we demonstrate that mature stem cell-derived intestinal and liver organoid cultures each express functional molecules that modulate bile acid uptake and recycling. These organoid cultures can be physically coupled in a Transwell system and …

Atypical Idiopathic Intracranial Hypertension Presenting As Cyclic Vomiting Syndrome: A Case Report, Nafee T Talukder, Amanda H Clorfeine, Moira K Black, Shade B Moody

Faculty, Staff and Student Publications

BACKGROUND: Idiopathic intracranial hypertension is a disorder of increased intracranial pressure in the absence of cerebrospinal outflow obstruction, mass lesion, or other underlying cause. It is a rare phenomenon in prepubertal children and is most typically found in women of childbearing age. The classic presentation consists of headaches, nausea, vomiting, and visual changes; however, children present more atypically. We report a case of idiopathic intracranial hypertension in an otherwise healthy, 4-year-old child with atypical symptoms resembling those of cyclic vomiting syndrome.
