Diabetic foot ulcer (DFU) is one of the serious complications of diabetes. It is the result of a joint effect of lower extremities vascular lesions, neuropathy, and infection, which require amputation and even threaten the life of the patient. At present, the conventional treatment for DFU includes infection control, wound care, wound reduction, reduction of foot pressure, use of dressings that are beneficial to wound surface healing, etc, but the effectiveness is not satisfactory. Recombinant human growth hormone and alginate dressing have been used in clinical, but there is lack of the relevant evidence of its effectiveness and safety, so this study evaluates the clinical effectiveness and safety of recombinant human growth hormone combined with alginate dressing in the treatment of DFU by systematic evaluation, the purpose is to provide a theoretical basis for the treatment of diabetic foot ulcer. ⋯ This study will give positive conclusions about the effectiveness and safety of recombinant human growth hormone combined alginate dressing in the treatment of DFU.

Rotator cuff disorders present a high retear rate despite advances in surgical treatment. Tissue engineering could therefore be interesting in order to try to enhance a more biological repair. RhBMP-2 is one of the most osteogenic growth factors and it also induces the formation of collagen type I. However, it has a short half-life and in order to get a more stable release over time it could be integrated in a more slowly degradable carrier, such as an alginate-chitin scaffold. The aim of this study was to investigate the role of the alginate-chitin scaffold alone and in combination with different concentrations of rhBMP-2 when applied on chronic rotator cuff lesions in a rat model. ⋯ The alginate-chitin scaffold seems to promote a more biological response after the reparation of a chronic rotator cuff lesion. Its effect is further enhanced by the addition of rhBMP-2 since the osteotendinous junction is more native-like and has better biomechanical properties.

Gastro-oesophageal reflux disease (GORD), a highly prevalent disease, is defined by troublesome symptoms and/or oesophageal lesions caused by reflux of gastric content. A diagnostic gold standard does not exist. A reliable diagnosis may be difficult in individual cases. ⋯ Proton pump inhibitors (PPI) are the drugs of first choice. In patients with insufficient PPI response, optimization of PPI therapy and/or combination with drugs having another mechanism of action are the available options. If PPIs are not sufficiently effective, not tolerated, or not wished antireflux procedures may be offered in specialized centers taking pathophysiological data into account.

The operative environment poses many challenges to studying the relationship between surgical acts and patient outcomes in intracranial oncological neurosurgery. We sought to develop a framework in which neurosurgical performance and extent of resection could be precisely quantified in a controlled setting. ⋯ The developed framework can offer clinicians, learners, and researchers the ability to perform operative rehearsal, teaching, and studies involving brain tumor surgery in a controlled laboratory environment and represents a crucial step in the understanding and training of expertise in neurosurgery.

Randomized Controlled TrialRandomised clinical trial: the effectiveness of Gaviscon Advance vs non-alginate antacid in suppression of acid pocket and post-prandial reflux in obese individuals after late-night supper.
Late-night supper increases the risk of postprandial reflux from the acid pocket especially in obesity. An alginate-based, raft-forming medication may be useful for obese patients with GERD. ⋯ Among obese individuals, Gaviscon Advance was superior to a non-alginate antacid in post-supper suppression of the acid pocket. (Clinical trial registration unique identifier: NCT03516188).
