Background: Achalasia is a rare esophageal motility disorder of unknown etiology, which leads to changes in the pressure and relaxation of the lower esophageal sphincter (LES), affecting peristalsis and contraction of the esophageal body. Dysphagia can impact individuals of any age, it is frequent in the elderly. Non-specific gastrointestinal symptoms are delayed and can give false diagnoses.

Collective continuity, the perception of the ingroup as an enduring temporal entity, has been linked with ingroup favouritism, negative attitudes and prejudice towards the outgroups. However, previous studies focused mainly on the perceived connection between the past and present of the group. We proposed that the expectation of a strong similarity between the present and future of the national ingroup, future collective continuity (FCC), positively affects present intergroup relations construals.

Radical esophagectomy remains the only potentially curative option in the treatment of esophageal cancer. However, this procedure is burdened with high morbidity and mortality rates, even in high-volume centers. A tracheo- or bronchoesophageal fistula (TBF) is rare but is one of the most difficult life-threatening complications following an esophagectomy for cancer treatment.

Article Synopsis
  • Trace elements play a crucial role in human health but can also be toxic; their absorption and effects are influenced by genetics, but this area is still under-researched.
  • This study conducted genome-wide analysis on 57 trace elements using blood samples from Scandinavian individuals, identifying 11 new genetic locations linked to the levels of specific elements such as arsenic, zinc, and selenium.
  • The findings suggest some trace elements may have weak to moderate health impacts, with notable indications of increased zinc potentially being harmful and linked to prostate cancer, though more validation is required.

Future self-perceptions seem to promote far-sighted decisions in intertemporal choices. Previous work suggested that future self-relatedness, the extent to which we feel similar and connected to our future self, is associated with moral concerns. We aimed to extend these findings to everyday moral judgments and behavior using experience sampling methods.

Idiopathic mediastinal fibrosis, also called sclerosing or fibrosing mediastinitis, is a very rare and aggressive fibroinflammatory process characterized by fibrous tissue proliferation in the mediastinal region. Herein, we present a rare case of idiopathic mediastinal fibrosis presenting with esophageal obstruction, most likely associated with immunoglobulin G (IgG4)-related disease, affecting the posterior mediastinum with intrapulmonary infiltration. Computed tomography revealed a narrowed lumen and thickened wall of the distal esophagus surrounded by a necrotic mass with infiltration into the nearby structures, suggesting a locally advanced malignant process.

Microplastics are small plastic fragments that are widely distributed in marine and terrestrial environments. While the soil ecosystem represents a large reservoir for plastic, research so far has focused mainly on the impact on aquatic ecosystems and there is a lack of information on the potentially adverse effects of microplastics on soil biota. Earthworms are key organisms of the soil ecosystem and are due to their crucial role in soil quality and fertility a suitable and popular model organism in soil ecotoxicology.
