Duodenal polyps have been reported in <1.5% of individuals who undergo esophagogastroduodenoscopy (EGD). We present a case of a 76-year-old male with recurrent hematemesis who was found to have an intestinal-type, pedunculated tubulovillous adenoma in the descending duodenum. An isolated occurrence of nonampullary sporadic duodenal adenoma is a rare finding. Presentation as an upper gastrointestinal hemorrhage is also extremely uncommon. Our patient's polyp was pedunculated, which is atypical, because most sporadic duodenal adenomas are morphologically flat or sessile. The purpose of this case is to present a rare cause of upper gastrointestinal bleeding and to depict characteristics of an isolated duodenal tubulovillous adenoma and its treatment options.

High-entropy metal-organic frameworks (HE-MOFs) hold promise as versatile materials, yet current rare examples are confined to low-valence elements in the fourth period, constraining their design and optimization for diverse applications. Here, a novel high-entropy, defect-rich and small-sized (32 nm) UiO-66 (ZrHfCeSnTi HE-UiO-66) has been synthesized for the first time, leveraging increased configurational entropy to achieve high tolerance to doping with diverse metal ions. The lattice distortion of HE-UiO-66 induces high exposure of metal nodes to create coordination unsaturated metal sites with a concentration of 322.

Inborn errors of selenoprotein expression arise from deleterious variants in genes encoding selenoproteins or selenoprotein biosynthetic factors, some of which are associated with neurodegenerative disorders. This study shows that bi-allelic selenocysteine tRNA-specific eukaryotic elongation factor (EEFSEC) variants cause selenoprotein deficiency, leading to progressive neurodegeneration. EEFSEC deficiency, an autosomal recessive disorder, manifests with global developmental delay, progressive spasticity, ataxia, and seizures.

Aromatase deficiency (ORPHA:91; OMIM: 613,546) is a rare, autosomal recessive disorder due to loss of function mutations in the CYP19A1 gene, described in both genders with an estimated incidence below 1/1000000. While in female the clinical manifestations generally occur at birth or in early infancy, and mainly involve sexual characteristics, in men clinical signs of aromatase deficiency mostly occur in puberty and especially in late puberty, so that diagnosis is generally established after the second decade due to tall stature, unfused epiphyses and reduced bone mass. Here we review the available information concerning the skeletal and extraskeletal phenotype and the clinical management of bone health in patients with aromatase CYP19A1 gene mutations.
