Development of a machine learning interatomic potential for exploring pressure-dependent kinetics of phase transitions in germanium.

We introduce a data-driven potential aimed at the investigation of pressure-dependent phase transitions in bulk germanium, including the estimate of kinetic barriers. This is achieved by suitably building a database including several configurations along minimum energy paths, as computed using the solid-state nudged elastic band method. After training the model based on density functional theory (DFT)-computed energies, forces, and stresses, we provide validation and rigorously test the potential on unexplored paths.

A bio-psycho-social approach in elderly population: outcome of adapted physical activity in patients with osteoarthritis.

Background: The beneficial effect of physical activity on a large spectrum of diseases is well known, with particular importance for elderly people. Among the different types of activity, adapted physical activity (APA) has been applied in a number of disease-related physical deficit.

Objective: The purpose of this study is to determine the outcome of a six months APA program in elder patients with osteoarthritis concerning physical and functional health and as second endpoint to determine the potential effect of AFA on reducing the risk of institutionalization.

Low incidence of pneumonia in COPD patients treated with inhaled corticosteroids undergoing pulmonary rehabilitation.

Background: Based on meta-analyses results, it is currently acknowledged that there is an increased risk of pneumonia in patients with chronic obstructive pulmonary disease (COPD) undergoing inhaled corticosteroids (ICS) treatment. However, this is not found to be true in those with asthma. No data on this risk are available for COPD patients involved in pulmonary rehabilitation program (PR).

Which immunotherapy product is better for patients allergic to Polistes venom? A laboratory and clinical study.

Background: Venom immunotherapy (VIT) is highly effective in preventing allergic reactions to insect stings, but the appropriate venom must be used to achieve clinical protection. In patients with multiple positive results to venoms, molecular allergy diagnostics or CAP-inhibition may identify the causative venom. Concerning allergy to venom from Polistes spp.

Efficient poly(3-hydroxypropionate) production from glycerol using Lactobacillus reuteri and recombinant Escherichia coli harboring L. reuteri propionaldehyde dehydrogenase and Chromobacterium sp. PHA synthase genes.

Poly(3-hydroxypropionate), P(3HP), is a polymer combining good biodegradability with favorable material properties. In the present study, a production system for P(3HP) was designed, comprising conversion of glycerol to 3-hydroxypropionaldehyde (3HPA) as equilibrium mixture with 3HPA-hydrate and -dimer in aqueous system (reuterin) using resting cells of native Lactobacillus reuteri in a first stage followed by transformation of the 3HPA to P(3HP) using recombinant Escherichia coli strain co-expressing highly active coenzyme A-acylating propionaldehyde dehydrogenase (PduP) from L. reuteri and polyhydroxyalkanoate synthase (PhaCcs) from Chromobacterium sp.

Impact of a chronic care model based on patient empowerment on the management of Type 2 diabetes: effects of the SINERGIA programme.

Aims: Several chronic care models for diabetes have been implemented in Italy, although conclusive data on their effectiveness are lacking. In the Cusano-Milanino diabetes clinic, patients with Type 2 diabetes with a stable disease/therapy (i.e.

Effects of pulmonary rehabilitation on exercise capacity in patients with COPD: a number needed to treat study.

Background: Pulmonary rehabilitation (PR) is recognized as an evidence-based treatment in improving dyspnea and quality of life in patients with COPD. We evaluated the number needed to treat (NNT) to achieve an increase in physical capacity, as defined by a significant improvement in the six-minute walk test (6MWT) in patients with COPD undergoing PR.

Methods: The study enrolled 284 patients aged 41 to 86 years (mean age 69.

Effects of replacing oxitropium with tiotropium on pulmonary function in patients with COPD: a randomized study.

Background: Inhaled bronchodilators are first line drugs in the treatment of chronic obstructive pulmonary disease (COPD). Tiotropium bromide is a recently introduced long-acting anticholinergic agent able to reduce dyspnoea and COPD exacerbations and to improve pulmonary function and quality of life. We designed a study to compare the short-term efficacy of tiotropium bromide with that of oxitropium bromide in improving pulmonary function in patients with COPD.
