Prevalence and Risk Factors of Oropharyngeal Dysphagia in Newly Diagnosed Head-and-Neck Cancer Patients.

Cancers (Basel)

December 2024

Department of Otorhinolaryngology, Head and Neck Surgery, Maastricht University Medical Center, P.O. Box 5800, 6202 AZ Maastricht, The Netherlands.

Background: Head-and-neck cancer (HNC) can cause oropharyngeal dysphagia (OD). Early identification of OD in newly diagnosed HNC patients is important to better prepare patients for their cancer treatment trajectory. The aim of this study is (1) to assess the prevalence of OD in HNC patients within three weeks before the start of cancer treatment and (2) to investigate which demographic and oncological characteristics may be risk factors associated with the risk of OD at baseline.

Anaemia is a frequent consequence of many gastrointestinal (GI) diseases in children and it can even be the initial presenting symptom of underlying chronic GI disease. The definition of anaemia is age and gender-dependent and it can be classified based on pathophysiology, red cell morphology, and clinical presentation. Although nutritional deficiencies, including GI malabsorption of nutrients and GI bleeding, play a major role, other pathophysiologic mechanisms seen in chronic GI diseases, whether inflammatory (e.

Introduction: Chronic nausea and vomiting are symptoms of a wide range of gastrointestinal and non-gastrointestinal conditions. Diagnosis can be challenging and requires a systematic and well-structured approach. If the initial investigation for structural, toxic and metabolic disorders is negative, digestive motility and gut-brain interaction disorders should be assessed.

Anorectal neuropathy causes anorectal dysfunction, yet it is poorly recognized. This stems from both a lack of understanding of the extrinsic and intrinsic innervation of the anorectum and tools for evaluation of neuronal function. Our objective was to provide an improved understanding of the neuronal networks of the anorectum and discuss its functional significance.

A H2S-activated NIR-II imaging probe for precise diagnosis and pathological evaluation of colorectal tumor.

Theranostics

January 2025

Lab of Molecular Imaging and Translational Medicine (MITM), Engineering Research Center of Molecular and Neuro Imaging, Ministry of Education, School of Life Science and Technology, Xidian University & International Joint Research Center for Advanced Medical Imaging and Intelligent Diagnosis and Treatment, Xi'an, Shaanxi, 710126, P. R. China.

The quick and accurate detection of colorectal cancer (CRC) is essential for improving the treatment efficacy and patient survival, which nevertheless remains challenging due to low specificity and sensitivity of current CRC diagnostic approaches. Therefore, providing a robust solution for real-time and accurate tumor delineation is highly desirable. We report a novel polyacrylic acid-mediated strategy to develop the endogenous hydrogen sulfide (HS)-activated NIR-II probe DCNP@PB for specific visualization of CRC and image-guided tumor surgery.

Article Synopsis
  • Refractory constipation (RC) in children is a unique condition that significantly affects the quality of life for both patients and their families.
  • Effective treatment for RC necessitates specialized diagnostic assessments and management strategies, often requiring a team of experts including pediatric neurogastroenterologists and potentially surgeons.
  • This document marks the first official position by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition addressing RC, outlining its definition, evaluation processes, and management approaches.

Faculty of Biology, Medicine, and Health, The University of Manchester, Manchester, UK; Department of Colorectal Surgery, Manchester University NHS Foundation Trust, Manchester, UK.

Introduction: Anal acoustic reflectometry (AAR), a novel test of anal sphincter function, was shown to predict a successful trial phase of sacral neuromodulation (SNM) for fecal incontinence. This follow-up study aims to explore if AAR can also predict short- and long-term SNM outcomes at less than and more than 5 y, respectively.

Methods: Outcome data were reviewed from a prospectively managed database.

To establish a consensus on the definition and management of idiopathic gastroparesis, international experts (selected by neurogastroenterology and motility societies and initiated by the Rome Foundation) devised 144 statements using the Delphi method, with at least 80% agreement required. This consensus defined idiopathic gastroparesis as the presence of symptoms associated with delayed gastric emptying in the absence of mechanical obstruction. Nausea and vomiting were identified as cardinal symptoms.

Building a Neurogastroenterology Unit: Why, Where, and How?

Visc Med

December 2024

Department of Internal Medicine and Gastroenterology, Helios Clinic Krefeld, Krefeld, Germany.

Background: Disorders of the gut-brain axis are public diseases ("Volkskrankheiten") and are among the most frequent reasons to visit a doctor. Despite their great medical and socio-economic importance, patients suffering from these disorders are often not taken seriously and, therefore, do not receive sufficient diagnostic evaluation, or a diagnosis, in conformity with the relevant guidelines. In addition, the inadequate compensation of services makes handling of neurogastroenterological disorders increasingly unattractive.

Article Synopsis
  • COVID-19 patients often show abnormal immune responses and mental health issues during hospitalization, but the connection with gut microbiome has not been fully explored.
  • The study classified COVID-19 severity into three levels: low (27.4%), moderate (29.8%), and critical (42.8%), with common symptoms including fever (66.1%) and cough (55.6%), and notable rates of anxiety (27.3%) and depression (39%).
  • Findings indicate that more severe cases exhibited higher levels of systemic inflammation and reduced gut bacterial diversity, particularly in women and obese individuals, suggesting a relationship between gut health, mental health, and COVID-19 severity, pointing to the potential of using microbiome-focused treatments.
