Introduction: Screening tests like colonoscopy can prevent colorectal cancer (CRC), yet their effectiveness is often questioned. The Nordic-European Initiative on Colorectal Cancer (NordICC) trial demonstrated that colonoscopy significantly reduces CRC incidence and mortality in per-protocol analysis. However, media coverage of the trial often focused on intention-to-screen findings that showed no change in mortality, possibly contributing to public confusion about colonoscopy benefits.

Glioblastoma multiforme (GBM) is a World Health Organisation (WHO) grade IV glioma originating from astrocytes. It is the most common malignant primary tumour of the brain and central nervous system (CNS) and is associated with fast progression and violent local spread, with a median overall survival of approximately 15 months after diagnosis. Due to its late and varied presentation, it is often diagnosed only after it has grown considerably.

Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are important causes of viral esophagitis mainly in immunocompromised individuals. Both viruses lead to development of focal ulcerations in the esophagus. While there have been rare case reports of esophagitis in immunocompetent individuals, there has not been a single reported case of coinfection with both CMV and EBV in an immunocompetent individual and presenting with diffuse esophageal ulceration.

This study aims to determine the effect of chronic hyperglycemia, induced by a high-fat diet and STZ-induced diabetes, on the development of Parkinson's disease-like characteristics. Understanding this relationship is crucial in pharmacology, neurology, and diabetes, as it could potentially lead to developing new therapeutic strategies for Parkinson's disease. Our study employed a comprehensive approach to investigate the effect of hyperglycemia on Parkinson's disease-like characteristics.

Article Synopsis
  • A 72-year-old woman with pre-existing health issues underwent an ERCP to remove bile duct stones but faced complications including abdominal pain and jaundice post-surgery.
  • During the ERCP, she experienced a drop in oxygen saturation and arrhythmia, leading to a diagnosis of gas embolism confirmed by imaging, revealing air bubbles in her heart.
  • Despite several emergency interventions, her condition worsened, and due to financial constraints, she was discharged against medical advice, highlighting the rarity and management difficulties of ERCP-related air embolism.

  • Budd-Chiari syndrome (BCS) involves blockage of the hepatic veins and is often linked to a condition that causes increased blood clotting.
  • Systemic amyloidosis is a disorder where misfolded proteins accumulate in the body, causing organ damage, and it typically leads to bleeding issues rather than clotting.
  • The case of a 40-year-old man illustrates how AL amyloidosis can lead to BCS, showing the importance of recognizing its varied and non-specific symptoms for accurate diagnosis.

Introduction: Upper gastrointestinal (UGI) cancers, comprising malignancies of the esophagus, stomach, duodenum, pancreas, liver, biliary tract, and gallbladder, are the second leading cause of cancer-related mortality in the United States and are associated with significant comorbidities. Recent studies show a disproportionate rise in pancreatic and stomach cancer among young adults. This study aims to use a nationwide, population-based cohort to (i) evaluate the trend of all UGI cancer as an aggregate and (ii) examine the role of demographics, histology, and tumor stage in UGI cancer incidence among young adults.

Background: Stool characteristics are used as a measure of ulcerative colitis (UC) disease activity, but they have not been validated against objective inflammation. We aimed to determine whether stool characteristics measured by trained artificial intelligence (AI) and physicians correlate with inflammation in UC.

Methods: Patients hospitalized with acute severe UC (ASUC) were asked to capture images of all bowel movements using a smartphone application (Dieta®).

Surgical clip migration into the common bile duct (CBD) with subsequent stone formation is an exceedingly rare complication following both laparoscopic and open cholecystectomy, with fewer than 100 cases reported in the literature. Herein, we present the case of a 78-year-old female who presented with abdominal pain and dark urine six years after an open cholecystectomy. Her abdominal ultrasonography revealed no abnormalities, with only mild derangements noted in liver function tests.

 Glioblastoma multiforme (GBM) is a malignant and aggressive primary brain tumor with a poor prognosis. This adverse prognosis is due to the tumor's tendency for advancement and recurrence caused by highly intrusive nature of the persisting GBM cells that actively escape from the main tumor mass into the surrounding normal brain tissue. On the basis of biomarker illustration, it can be classified into molecular subgroups.

There is sparse literature on the development of malignancy in remnant gastric stomach after bariatric Roux-en-Y gastric bypass surgery. We report a case of overt upper gastrointestinal bleeding from malignant adenocarcinoma in the remnant stomach presenting several years after bariatric Roux-En-Y gastric bypass surgery. The mass in the remnant stomach was surgically resected, and the patient was subsequently diagnosed with Lynch syndrome on genetic analysis.

Background: Obesity is an independent risk factor for the development of hepatocellular carcinoma (HCC) and may influence its outcomes. However, after diagnosis of HCC, like other malignancies, the obesity paradox may exist where higher body mass index (BMI) may in fact confer a survival benefit. This is frequently observed in patients with advanced HCC and cirrhosis, who often present late with advanced tumor features and cancer related weight loss.

Parkinson's disease (PD) is a progressive neurodegenerative disorder that deals with dopaminergic deficiency in Substantia nigra pars compact (SNpc) region of the brain. Dopaminergic deficiency manifests into motor dysfunction. Alpha-synuclein protein aggregation is the source for inception of the pathology.

Rice is a major staple food, and, hence, doubling its productivity is critical to sustain future food security. Improving photosynthesis, source-sink relationships and grain-filling mechanisms are promising traits for improvement in grain yield. To understand the source-sink relationship and grain yield, a set of contrasting rice genotypes differing in yield and biomass were studied for physiological, biochemical and gene-expression differences.

  • The review focuses on toxoplasmosis rates in Panama and Colombia, analyzing data on seroprevalence and risk factors.
  • Studies showed seroprevalence in Ciudad de Panamá ranged from 22% to 44%, with higher rates linked to poverty and closeness to water.
  • Heat maps and mathematical models were created to pinpoint areas that need targeted healthcare campaigns for congenital toxoplasmosis and infections.

Introduction: Comprehensive primary care is a key component of any good health system. Designers need to incorporate the requirements of (i) a defined population, (ii) comprehensive range, (iii) continuity of services, and (iv) easy accessibility, as well as address several related issues. They also need to keep in mind that the classical British GP model, because of the severe challenges of physician availability, is all but infeasible for most developing countries.

Article Synopsis
  • The purpose of the review was to develop and assess educational materials aimed at reducing disease burdens from infections in Panama, Colombia, and the USA.
  • Recent findings indicate that educational programs in these countries have not yet been evaluated for their effectiveness, despite being implemented for various demographics like high school students and pregnant women.
  • The summary highlights that these educational materials have shown short-term benefits in disseminating information, with future goals focusing on conducting long-term studies, updating materials based on new research, and increasing access to these resources for broader public health impact.

Biomedical devices are prone to blood clot formation (thrombosis), and liquid-infused surfaces (LIS) are effective in reducing the thrombotic response. However, the mechanisms that underpin this performance, and in particular the role of the lubricant, are not well understood. In this work, it is investigated whether the mechanism of LIS action is related to i) inhibition of factor XII (FXII) activation and the contact pathway; ii) reduced fibrin density of clots formed on surfaces; iii) increased mobility of proteins or cells on the surface due to the interfacial flow of the lubricant.
