RESUMO

BACKGROUND: Flexible endoscopic myotomy has been increasingly performed for Zenker's diverticulum using various endoscopic techniques and devices. The main aims of this study were to assess practice patterns and compare outcomes of endoscopic myotomy for Zenker's diverticulum. METHODS: Procedures performed at 12 tertiary endoscopy centers from 1/2012 to 12/2018 were reviewed. Patients (≥ 18 years) with Zenker's diverticulum who had dysphagia and/or regurgitation and underwent endoscopic myotomy were included. Outcomes assessed included technical success, clinical success, and adverse events. RESULTS: 161 patients were included. Traditional endoscopic septotomy was performed most frequently (137/161, 85.1 %) followed by submucosal dissection of the septum and myotomy (24/161, 14.9 %). The hook knife (43/161, 26.7 %) and needle-knife (33/161, 20.5 %) were used most frequently. Overall, technical and clinical success rates were 98.1 % (158/161) and 78.1 % (96/123), respectively. Adverse events were noted in 13 patients (8.1 %). There was no significant difference in technical and clinical success between traditional septotomy and submucosal dissection groups (97.1 % vs. 95.8 %, P = 0.56 and 75.2 % vs. 90.9 %, P  = 0.16, respectively). Clinical success was higher with the hook knife (96.7 %) compared with the needle-knife (76.6 %) and insulated tip knife (47.1 %). Outcomes were similar between centers performing > 20, 11 - 20, and ≤ 10 procedures. CONCLUSIONS: Flexible endoscopic myotomy is an effective therapy for Zenker's diverticulum, with a low rate of adverse events. There was no significant difference in outcomes between traditional septotomy and a submucosal dissection approach, or with centers with higher volume, though clinical success was higher with the hook knife.

RESUMO

BACKGROUND AND AIMS: Various gastrointestinal societies have released guidelines on the evaluation of asymptomatic pancreatic cysts (PCs). These guidelines differ on several aspects, which create a conundrum for clinicians. The aim of this study was to evaluate preferences and practice patterns in the management of incidental PCs in light of these societal recommendations. METHODS: An electronic survey distributed to members of the American Society for Gastrointestinal Endoscopy (ASGE). Main outcomes included practice setting (academic vs. community), preferences for evaluation, management, and surveillance strategies for PCs. RESULTS: A total of 172 subjects completed the study (52% academic-based endoscopists). Eighty-six (50%) and 138 (80%) of the participants responded that they would recommend EUS surveillance of incidental PCs measuring less than 2 cm and 3 cm, respectively. Nearly half of the endosonographers (42.5% community and 44% academic; p = 1.0) would routinely perform FNA on PCs without any high-risk features. More academic-based endoscopists (57% academic vs. 32% community; p = 0.001) would continue incidental PC surveillance indefinitely. CONCLUSIONS: There is significant variability in the approach of incidental PCs among clinicians, with practice patterns often diverging from the various GI societal guideline recommendations. Most survey respondents would routinely recommend EUS-FNA and indefinite surveillance for incidental PCs without high-risk features. The indiscriminate use of EUS-FNA and indefinite surveillance of all incidental PCs is not cost-effective, exposes the patient to unnecessary testing, and can further perpetuate diagnostic uncertainty. Well-designed studies are needed to improve our diagnostic and risk stratification accuracy in order to formulate a consensus on the management of these incidental PCs.

RESUMO

Designer drugs represent an increasingly popular form of recreational substance abuse, especially amongst young adults. The two classes of designer drugs that have recently risen to prominence are the synthetic cannabinoids and synthetic cathinones. These substances are not detected by conventional drug screening methods and can often be associated with serious health consequences, including seizures, renal failure and death. Thus, clinicians should be familiar with the signs, symptoms, and toxicities associated with the use of these substances, and maintain a high level of suspicion for synthetic drugs as an alternative means of "getting high." We present a case of a 20-year-old college student who presented to the emergency department with altered mental status and severe agitation who later admitted to using bath salts. The goal of this article is to raise awareness about these new designer drugs, their clinical presentation, and management of their intoxication.

RESUMO

According to the available studies, mobile applications have provided significant support in improving the diverse skills of special individuals with social pragmatic communication disorder (SPCD). Over the last decade, SPCD has affected 8 to 11% of individuals, and therapy sessions cost between $50 and $150 per hour. This preliminary study aims to develop an interactive, user-friendly intervention to enhance social and emotional interaction skills in individuals with SPCD. The proposed intervention is an Android application that enhances social and emotional interaction skills. This pilot study involved 29 human subjects aged 7-13 years with pragmatic communication deficits. In a randomized controlled trial, the intervention was developed and implemented with consideration of caregiver and professional requirements. The improvement was analyzed using standard scales, including the Social Communication Questionnaire (SCQ) and the Social Communication Disorder Scale (SCDS). Moreover, the outcomes were examined through statistical parameters (mean, standard deviation) and tests (t-test). The intervention significantly improved the social and emotional skills of individuals with deficits. Before using the intervention, the identified statistical values for SCQ (mean = 6.48 and standard deviation = 3.37) and SCDS (mean = 8.17 and standard deviation = 4.79). However, after using the intervention, values for SCQ (mean = 8.24 and standard deviation = 3.95) and SCDS (mean = 9.48 and standard deviation = 4.72) were improved in comparison to the before-intervention outcome. The evaluation of the t-scores and p-values indicates that there has been significant improvement in the performance of individuals after the successful completion of the intervention. The proposed and applied intervention resulted in a significant impact in terms of improvement in social and emotional skills. The study concluded that it allows individuals to practice social and emotional interaction skills in a structured, controlled, and interactive environment. The proposed intervention has been found acceptable as per the reviews of caregivers and professionals, based on essential criteria including user experience, usability, interactive nature, reliability, and creditability.

RESUMO

In this day and age, depression is still one of the biggest problems in the world. If left untreated, it can lead to suicidal thoughts and attempts. There is a need for proper diagnoses of Major Depressive Disorder (MDD) and evaluation of the early stages to stop the side effects. Early detection is critical to identify a variety of serious conditions. In order to provide safe and effective protection to MDD patients, it is crucial to automate diagnoses and make decision-making tools widely available. Although there are various classification systems for the diagnosis of MDD, no reliable, secure method that meets these requirements has been established to date. In this paper, a federated deep learning-based multimodal system for MDD classification using electroencephalography (EEG) and audio datasets is presented while meeting data privacy requirements. The performance of the federated learning (FL) model was tested on independent and identically distributed (IID) and non-IID data. The study began by extracting features from several pre-trained models and ultimately decided to use bidirectional short-term memory (Bi-LSTM) as the base model, as it had the highest validation accuracy of 91% compared to a convolutional neural network and LSTM with 85% and 89% validation accuracy on audio data, respectively. The Bi-LSTM model also achieved a validation accuracy of 98.9% for EEG data. The FL method was then used to perform experiments on IID and non-IID datasets. The FL-based multimodal model achieved an exceptional training and validation accuracy of 99.9% when trained and evaluated on both IID and non-IIID datasets. These results show that the FL multimodal system performs almost as well as the Bi-LSTM multimodal system and emphasize its suitability for processing IID and non-IIID data. Several clients were found to perform better than conventional pre-trained models in a multimodal framework for federated learning using EEG and audio datasets. The proposed framework stands out from other classification techniques for MDD due to its special features, such as multimodality and data privacy for edge machines with limited resources. Due to these additional features, the framework concept is the most suitable alternative approach for the early classification of MDD patients.

RESUMO

Prognostic survival prediction in colorectal cancer (CRC) plays a crucial role in guiding treatment decisions and improving patient outcomes. In this research, we explore the application of deep learning techniques to predict survival outcomes based on histopathological images of human colorectal cancer. We present a retrospective multicenter study utilizing a dataset of 100,000 nonoverlapping image patches from hematoxylin & eosin-stained histological images of CRC and normal tissue. The dataset includes diverse tissue classes such as adipose, background, debris, lymphocytes, mucus, smooth muscle, normal colon mucosa, cancer-associated stroma, and colorectal adenocarcinoma epithelium. To perform survival prediction, we employ various deep learning architectures, including convolutional neural network, DenseNet201, InceptionResNetV2, VGG16, VGG19, and Xception. These architectures are trained on the dataset using a multicenter retrospective analysis approach. Extensive preprocessing steps are undertaken, including image normalization using Macenko's method and data augmentation techniques, to optimize model performance. The experimental findings reveal promising results, demonstrating the effectiveness of deep learning models in prognostic survival prediction. Our models achieve high accuracy, precision, recall, and validation metrics, showcasing their ability to capture relevant histological patterns associated with prognosis. Visualization techniques are employed to interpret the models' decision-making process, highlighting important features and regions contributing to survival predictions. The implications of this research are manifold. The accurate prediction of survival outcomes in CRC can aid in personalized medicine and clinical decision-making, facilitating tailored treatment plans for individual patients. The identification of important histological features and biomarkers provides valuable insights into disease mechanisms and may lead to the discovery of novel prognostic indicators. The transparency and explainability of the models enhance trust and acceptance, fostering their integration into clinical practice. Research demonstrates the potential of deep learning models for prognostic survival prediction in human colorectal cancer histology. The findings contribute to the understanding of disease progression and offer practical applications in personalized medicine. By harnessing the power of deep learning and histopathological analysis, we pave the way for improved patient care, clinical decision support, and advancements in prognostic prediction in CRC.

RESUMO

OBJECTIVE: The aim of the present work was to propose and implement deep neural network (DNN)-based handheld diagnosis system for more accurate diagnosis and severity assessment of individuals with autism spectrum disorder (ASD). METHODS: Initially, the learning of the proposed system for ASD diagnosis was performed by implementing DNN algorithms such as a convolutional neural network (CNN) and long short-term memory (LSTM), and multilayer perceptron (MLP) with DSM-V based acquired dataset. The performance of the DNN algorithms was analyzed based on parameters viz. accuracy, loss, mean squared error (MSE), precision, recall, and area under the curve (AUC) during the training and validation process. Later, the optimum DNN algorithm, among the tested algorithms, was implemented on handheld diagnosis system (HDS) and the performance of HDS was analyzed. The stability of proposed DNN-based HDS was validated with the dataset group of 20 ASD and 20 typically developed (TD) individuals. RESULTS: It was observed during comparative analysis that LSTM resulted better in ASD diagnosis as compared to other artificial intelligence (AI) algorithms such as CNN and MLP since LSTM showed stabilized results achieving maximum accuracy in less consumption of epochs with minimum MSE and loss. Further, the LSTM based proposed HDS for ASD achieved optimum results with 100% accuracy in reference to DSM-V, which was validated statistically using a group of ASD and TD individuals. CONCLUSION: The use of advanced AI algorithms could play an important role in the diagnosis of ASD in today's era. Since the proposed LSTM based HDS for ASD and determination of its severity provided accurate results with maximum accuracy with reference to DSM-V criteria, the proposed HDS could be the best alternative to the manual diagnosis system for diagnosis of ASD.

RESUMO

OBJECTIVE: Today, most of the individuals with Autism Spectrum Disorders (ASD) have atypical sensory behaviors. The main aim of this study is to propose an assistive intervention for supporting the overloaded sensory responses in hypersensitive individuals with ASD. METHODS: The vision, auditory, smell, and physical balance related multi-sensors based hardware prototype, namely Assistive Companion for Hypersensitive Individuals (ACHI) has been designed for individuals with ASD. The proposed ACHI prototype is an assistive-technology based companion for hypersensitive individuals with ASD which is able to 'fetch/detect the sensory information using electronic sensors', 'making the decision using fuzzy logic on the basis of fetched sensory information' and then, 'transmit the generated information over the internet through the Internet of Things (IoT)', and also able for 'generating alerts to caregivers'. The proposed design is also capable of providing audio & video feedback to calm down individuals with ASD. RESULTS: After testing, it is observed that 93% percent of the caregivers rated the proposed ACHI intervention on the scale of above average. The remarkable reduction in hyperactive states related triggering incidents in ASD has been found with the use of ACHI. CONCLUSION: The present work and the proposed prototype can identify and control the sensory overload triggers in ASD and it can guide the caregiver or clinicians to optimize the responsible surrounding causes of explosive behavior in ASD and would help the individuals with ASD to become calm.

RESUMO

BACKGROUND/AIMS: To analyze the incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) sepsis in the early (July to September) and later (October to June) academic months to assess the "July effect". METHODS: The National Inpatient Sample (2010-2014) was used to identify ERCP-related adult hospitalizations at urban teaching hospitals by applying relevant procedure codes from the International Classification of Diseases, 9th revision, Clinical Modification. Post-ERCP outcomes were compared between the early and later academic months. A multivariate analysis was performed to evaluate the odds of post-ERCP sepsis and its predictors. RESULTS: Of 481,193 ERCP procedures carried out at urban teaching hospitals, 124,934 were performed during the early academic months. The demographics were comparable for ERCP procedures performed during the early and later academic months. A higher incidence (9.4% vs. 8.8%, p<0.001) and odds (odds ratio [OR], 1.07) of post-ERCP sepsis were observed in ERCP performed during the early academic months. The in-hospital mortality rate (7% vs. 7.5%, p=0.072), length of stay, and total hospital charges in patients with post-ERCP sepsis were also equivalent between the 2 time points. Pre-ERCP cholangitis (OR, 3.20) and post-ERCP complications such as cholangitis (OR, 6.27), perforation (OR, 3.93), and hemorrhage (OR, 1.42) were significant predictors of higher post-ERCP sepsis in procedures performed during the early academic months. CONCLUSION: The July effect was present in the incidence of post-ERCP sepsis, and academic programs should take into consideration the predictors of post-ERCP sepsis to lower health-care burden.

RESUMO

We present a rare case of a 46-year-old man presenting with mucinous ascites secondary to malignant peritoneal mesothelioma (MPM) that was diagnosed via colonoscopy with biopsies. Both our findings and the clinical presentation were unique. While it is widely known that asbestos exposure is commonly associated with pleural mesothelioma, 6-10% of malignant mesotheliomas arise from the peritoneum. To date, only 4 cases of MPM with the primary tumor site in the colon have been described in the literature.

RESUMO

BACKGROUND: Adherence to quality indicators and surveillance guidelines in the management of Barrett's esophagus (BE) promotes high-quality, cost-effective care. The aims of this study were (1) to evaluate adherence to standardized classification (Prague Criteria) and systematic (four-quadrant) biopsy protocol, (2) to identify predictors of practice patterns, and (3) to assess adherence to surveillance guidelines for non-dysplastic BE (NDBE). METHODS: This was a single-center retrospective study of esophagogastroduodenoscopy (EGD) performed for BE (June 2008 to December 2015). Patient demographics, procedure characteristics, and histology results were obtained from the procedure report-generating database and chart review. Adherence to Prague Criteria and systematic biopsies was based on operative report documentation. Multiple logistic regression analysis was performed to identify predictors of practice patterns. Guideline adherent surveillance EGD was defined as those performed within 6 months of the recommended 3- to 5-year interval. RESULTS: In total, 397 patients (66.5 % male; mean age 60.1 ±â€Š12.5 years) had an index EGD during the study period. Adherence to Prague Criteria and systematic biopsies was 27.4 % and 24.1 %, respectively. Endoscopists who performed therapeutic interventions for BE were more likely to use the Prague Criteria (OR: 3.16; 95 %CI: 1.47 - 6.82; P  < 0.01) than those who did not. Longer time in practice was positively associated with adherence to Prague Criteria (OR 1.07; 95 %CI: 1.02 - 1.12; P  < 0.01) but with a lower likelihood of performing systematic biopsies (OR 0.91; 95 %CI: 0.85 - 0.97; P  < 0.01). More than half (55.6 %) of patients with NDBE underwent surveillance EGD sooner (range 1 - 29 months) than the recommended interval. CONCLUSION: Adherence to quality indicators and surveillance guidelines in BE is low. Operator characteristics, including experience with endoscopic therapy for BE and time in practice predicted practice pattern. Future efforts are needed to reduce variability in practice and promote high-value care.

RESUMO

BACKGROUND: After inpatient management of upper gastrointestinal bleeding (GIB) due to peptic ulcer disease (PUD), oral proton pump inhibitor (PPI) therapy is recommended at discharge to decrease rebleeding risk and improve ulcer healing. Our aim is to determine whether once-daily oral PPI dosing at hospital discharge is associated with inferior 30-day rebleeding outcomes as compared to twice-daily dosing. METHODS: We retrospectively identified 233 patients admitted with signs and symptoms of upper GIB found to be due to PUD on upper endoscopy. After inpatient management, patients discharged on once-daily oral PPI were compared to those discharged on twice-daily therapy. We utilized propensity score matching based on Rockall scores to ensure the two groups were closely matched in terms of their baseline rebleeding risk. Primary outcome was the incidence of rebleeding within 30 days. Secondary outcomes were all-cause mortality, blood transfusion requirement, requirement for interventional radiology or surgery. RESULTS: Overall, 49 patients were discharged on once-daily and 184 on twice-daily PPI. Recurrent bleeding occurred in 18 patients (7.7%) within 30 days. There was no statistically significant difference in recurrent bleeding rates between once-daily (n = 7, 14.3%) as compared to twice-daily PPI (n = 11, 6%) (P = 0.053). In a 1:1 propensity score matched analysis, there was no statistically significant difference in 30-day recurrent bleeding rate between groups (14% once-daily vs. 4% twice-daily, P = 0.159). There were no differences in secondary outcomes. CONCLUSIONS: Once-daily oral PPI dosing at hospital discharge was not associated with inferior outcomes compared to twice-daily dosing in patients hospitalized for upper GIB due to PUD.

RESUMO

Abdominal tuberculosis (TB) is an uncommon entity in the United States. Colonic TB is reported in 2-3% of patients with abdominal TB. It is frequently misdiagnosed as Crohn's disease or carcinoma of the colon due to their shared clinical, radiographic, and endoscopic presentations. We present a case of a 72-year-old male with colonic tuberculosis presenting as hematochezia. Our patient presented with shortness of breath and weight loss. Chest X-ray demonstrated ill-defined bilateral parenchymal opacities in the perihilar, mid, and lower lung zones. The patient was diagnosed and treated for community acquired pneumonia, with no improvement. Hematochezia complicated by symptomatic hypotension developed later in the course of admission. Colonoscopy revealed multiple ulcers at the anus and transverse and ascending colon as well as the cecum with stigmata of bleeding. Biopsy of a sigmoid ulcer was consistent with colonic tuberculosis. Antitubercular therapy was initiated, but the patient passed away secondary to multiorgan failure 29 days into admission.

RESUMO

A previously healthy man aged 50 years presented with malaise, anorexia, abdominal pain, nausea, vomiting, generalised jaundice, scleral icterus and dark urine. He was not on any prescription or over-the-counter medications, but reported drinking 4-5 energy drinks daily for 3 weeks prior to presentation. Physical examination revealed jaundice and right upper quadrant abdominal tenderness. Laboratory studies were remarkable for transaminitis and evidence of chronic hepatitis C infection. Ultrasound scan demonstrated an echogenic liver and diffuse gallbladder wall thickening. Liver biopsy showed severe acute hepatitis with bridging necrosis and marked cholestasis. The patient was treated supportively with complete resolution of his symptoms and marked improvement in his laboratory abnormalities. The development of acute hepatitis in this patient was likely secondary to excessive energy drink consumption. Energy drinks as well as other herbal/over-the-counter supplements should be considered by clinicians in the workup of patients with acute hepatitis, particularly once other aetiologies have been excluded.

RESUMO

Chronic hepatitis C infection is the leading cause of chronic liver disease, cirrhosis, hepatocellular carcinoma as well as the primary indication for liver transplantation in the United States. Despite recent advances in drugs for the treatment of hepatitis C, predictive models estimate the incidence of cirrhosis due to hepatitis C infection will to continue to rise for the next two decades. There is currently an immense interest in the treatment of patients with fibrosis and early-stage cirrhosis as treatment can lead to decrease in the rates of decompensated cirrhosis, hepatocellular carcinoma and need for liver transplantation in these patients. The goal of this paper is to provide clinicians and health care professionals further information about the treatment of patients with hepatitis C infection and cirrhosis. Additionally, the paper focuses on the disease burden, epidemiology, diagnosis and the disease course from infection to treatment. We provide an overview of multiple studies for the treatment of chronic hepatitis C infection that have included patients with cirrhosis. We also discuss the advantages and disadvantages of treatment in cirrhotic patients and focus on the most up to date guidelines available for treatment.

RESUMO

INTRODUCTION: The utilization of esophagogastroduodenoscopy (EGD) and related procedures continues to rise. Due to this increase in utilization is an inevitable rise in serious complications such as hemorrhage and perforation. One understudied and dreaded complication of EGD causing significant morbidity and mortality is duodenal perforation. PRESENTATION OF CASE: We present the case of a 63-year-old male who presented to our institution's emergency room with dyspepsia, melanic stools, tachycardia, and hypotension. Initial laboratory evaluation was significant for severe anemia, lactic acidosis, and acute kidney injury, while CT scan of the abdomen pelvis did not suggest retroperitoneal hematoma or bowel perforation. An emergent EGD was performed which showed multiple bleeding duodenal ulcers that were cauterized and injected with epinephrine. Post-procedure the patient developed worsening abdominal pain, distension, diaphoresis, and tachypnea, requiring emergent intubation. A CT scan of the abdomen and pelvis with oral contrast confirmed pneumoperitoneum and duodenal perforation. DISCUSSION: Due to the patient's hemodynamic instability and multiple comorbidities, he was treated non-operatively with strict bowel rest and intravenous antibiotics. The patient ultimately had a 19-day hospital course complicated by renal failure requiring hemodialysis and an ischemic limb necessitating above knee amputation. CONCLUSION: This case describes an unsuccessful attempt at nonoperative management of duodenal perforation following EGD.

RESUMO

Non-alcoholic fatty liver disease (NAFLD) is currently the third most common indication for liver transplantation in the United States. With the growing incidence of obesity, NAFLD is expected to become the most common indication for liver transplantation over the next few decades. As the number of patients who have undergone transplantation for NAFLD increases, unique challenges have emerged in the management and long-term outcomes in patients. Risk factors such as obesity, hypertension, diabetes, and hyperlipidemia continue to play an important role in the pathogenesis of the disease and its recurrence. Patients who undergo liver transplantation for NAFLD have similar long-term survival as patients who undergo liver transplantation for other indications. Research shows that post-transplantation recurrence of NAFLD is commonplace with some patients progressing to recurrent non-alcoholic steatohepatitis and cirrhosis. While treatment of comorbidities is important, there is no consensus on the management of modifiable risk factors or the role of pharmacotherapy and immunosuppression in patients who develop recurrent or de novo NAFLD post-transplant. This review provides an outline of NAFLD as indication for liver transplantation with a focus on the epidemiology, pathophysiology and risk factors associated with this disease. It also provides a brief review on the pre-transplant considerations and post-transplant factors including patient characteristics, role of obesity and metabolic syndrome, recurrence and de novo NAFLD, outcomes post-liver transplantation, choice of medications, and options for immunosuppression.

The authors report a case of a 31-year-old woman from India with history of seizure disorder who presented with sudden onset right hemiparesis and right-sided upper motor neuron type facial palsy. No identifiable risk factors were noted on admission and all laboratory investigations were negative. MR angiography helped in arriving at the diagnosis of moyamoya disease as the aetiology of her symptoms.
