We fabricated ultrathin metal - oxide - semiconductor (MOS) nanocapacitors using atomic layer deposition. The capacitors consist of a bilayer of Al2O3 and Y2O3 with a total thickness of ~10 nm, deposited on silicon substrate. The presence of the two materials, each slab being ~5 nm thick and uniform over a large area, was confirmed with Transmission Electron Microscopy and X-ray photoelectron spectroscopy (XPS).

Background: Home Enteral Nutrition (HEN) is used to prevent or correct malnutrition in outpatients. Due to the complexity of this process, the indication, follow-up, and results of an educational program of HEN patients was evaluated.

Methods: A prospective, observational, real-life, multicenter study was performed in 21 Spanish Hospital.

Article Synopsis
  • The study investigates the link between persistent organic pollutants (POPs) in visceral adipose tissue and metabolic syndrome (MetS) in patients undergoing surgery, highlighting how POP accumulation might be a significant risk factor for MetS.* -
  • A total of 117 patients were assessed, revealing that 35% showed clinical signs of MetS; specific organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were analyzed in their adipose tissue samples, with linear and logistic regression models applied to determine associations.* -
  • Results indicated a positive correlation between waist circumference and all tested OCP concentrations, with specific pollutants like HCB and γ-HCH being significantly associated with increased odds

Objectives: Compliance in outpatients with gastrointestinal (GI) malabsorption is key in nutritional treatment. The objective of this study was to assess compliance in patients with GI impairment and malnutrition taking a high-calorie, high-protein, peptide-based oral nutritional supplement (ONS-PBD).

Methods: A prospective, multicenter, observational study was conducted in 19 medical sites in Spain where ONS-PBD were prescribed as standard of care.
