Article Synopsis
  • Bismuth quadruple therapies (BQTs) have been effective in treating Helicobacter pylori infections in Europe, particularly in the face of antibiotic resistance, with notable use increasing from 8.6% in 2013 to 39% in 2021.
  • An analysis of data from nearly 50,000 patients indicated that the single-capsule BQT was the most common regimen and achieved over 90% effectiveness with certain combinations.
  • Key factors that improved treatment success included adherence to the regimen, use of high-dose proton pump inhibitors, and implementing the therapy as a first-line treatment.

Virtual reality (VR) and hypnosis (H) are useful pain management tools, but the potential benefit of their combination (VRH) has yet to be studied. This study examines the user experience of VRH, compared to H and VR alone, using interviews following an experimental study examining the effect of the three interventions on pain perception. Following a within-subjects repeated measures experimental design, 16 participants received the three interventions during which they received painful electrical stimuli.

Introduction: Gastric cancer (GC) is one of the most lethal malignancies worldwide. Helicobacter pylori is the primary cause of GC; therefore, its eradication reduces the risk of developing this neoplasia. There is extensive evidence regarding quadruple therapy with relevance to the European population.

  • A study examined how different reasons for testing for Helicobacter pylori (H. pylori) affect treatment prescriptions and their success rates across Europe from 2013 to 2023.
  • Out of 53,636 cases, the most common reasons for testing included dyspepsia with normal endoscopy and various types of ulcers, with treatment effectiveness ranging from 87% to 91% based on the indication.
  • Patients with ulcers and preneoplastic lesions experienced higher treatment success and compliance, while those tested for dyspepsia had higher rates of adverse effects.

Background: non-bismuth sequential therapy (SEQ) was suggested as a first-line anti- treatment alternative to standard triple therapy (STT).

Methods: We conducted a systematic review with a meta-analysis of randomized controlled trials (RCTs) comparing the efficacy of 10-day SEQ vs. STT (of at least 7 days) using bibliographical searches up to July 2021, including treatment-naïve adult or children.

Article Synopsis
  • - The management of Helicobacter pylori infection involves a combination of proton pump inhibitors (PPIs) and antibiotics to effectively eradicate the bacteria, as evaluated by the European Registry on Helicobacter pylori management (Hp-EuReg).
  • - Analysis of data from 36,579 patients across five countries revealed that 14-day treatments with specific antibiotic combinations and high-dose PPIs resulted in optimal effectiveness, while 10- and 14-day therapies with high-dose PPIs were also successful.
  • - The study concludes that for first-line treatment, the use of high-dose PPIs is recommended, especially in certain combinations and durations, while shorter 7-day therapies showed suboptimal results.

Article Synopsis
  • Antibiotic resistance significantly affects the treatment success rates for Helicobacter pylori infections, with noted resistance levels in Europe.
  • A study analyzed 2,852 naive patients and found that the 3-in-1 single capsule with bismuth, metronidazole, and tetracycline, as well as a quadruple therapy with bismuth, had the highest effectiveness against H. pylori, even with existing resistances.
  • For non-naive patients, resistance was even higher, but the same 3-in-1 capsule and triple therapy with levofloxacin showed promising results, highlighting the need for effective treatment options based on resistance patterns.

The segmentation of patients into homogeneous groups could help to improve eradication therapy effectiveness. Our aim was to determine the most important treatment strategies used in Europe, to evaluate first-line treatment effectiveness according to year and country. : All first-line empirical treatments registered at AEGREDCap in the European Registry on management (Hp-EuReg) from June 2013 to November 2022.

Pesticide use has increased in the Lake Tana sub-basin due to increased agricultural activity, potentially endangering nontargeted organisms. To assess its potential impact on fish health and fish-consuming human populations, pesticide concentrations in the fillet and liver tissue of three fish species, namely Labeobarbus megastoma, Labeobarbus tsanensis, and Oreochromis niloticus, were investigated in Lake Tana. Fish samples were taken from the lake near the rivers of Ribb and Gumara, which flow through agricultural areas where considerable amounts of pesticides have been applied.

Article Synopsis
  • A study evaluated the effectiveness and safety of single capsule bismuth quadruple therapy (scBQT) administered three times a day, as opposed to the recommended four times a day schedule, focusing on ease of adherence.
  • Out of 3,712 cases analyzed, the three times a day regimen showed a higher cure rate of 94% compared to 91% for the four times a day schedule, though adherence and safety were similar.
  • The findings suggest that the three times a day scBQT regimen is more effective, with factors like treatment adherence and the type of proton pump inhibitor used being significant predictors of infection cure.

Background And Aims: Several methods are available to diagnose infection. Our objective was to evaluate the tests used for both the initial diagnosis and the confirmation of eradication after treatment in Europe.

Methods: The European Registry on the management of infection is an international, multicentre, prospective, non-interventional registry aiming to evaluate the management of -infected patients in Europe.

Vermiform appendix torsion is a rare condition that mimics acute appendicitis and is diagnosed during surgery. On the other hand, pylephlebitis (or septic thrombophlebitis) is a complication that occurs due to occlusive thrombosis of mesenteric venous system branches secondary to intra-abdominal infections. Although rare since the antibiotic era, it must be considered in the differential diagnosis of postoperative fever.

Background: Achieving post-anesthesia discharge criteria after surgery or outpatient procedures does not mean that the patient has regained all his or her faculties, such as driving. Although mandated by many clinical guidelines, there is no evidence that escort-drivers reduce the risk of traffic accidents after deep sedation. The purpose of this study was to evaluate that hypothesis that driving performance as measured using a driving simulation would not differ between patients who had undergone deep sedation for gastrointestinal endoscopy meeting discharge criteria and their escorts.

Background: Patient referral is a process in which a healthcare provider decides to seek assistance due to the limitations of available skills, resources and services offered locally. Paper-based referrals predominantly used in low-income countries hardly follow any procedure. This causes a major gap in communication, coordination, and continuity of care between primary and specialized levels, leading to poor access, delay, duplication and unnecessary costs.
