Impairment of lung volume perception and breathing control in hypermobile Ehlers-Danlos syndrome.

Breathing difficulties and exertional dyspnea are frequently reported in hypermobile Ehlers-Danlos syndrome (hEDS); however, they are not clearly explained. An impaired proprioception or the addition of a cognitive task could influence ventilatory control. How can the perception of lung volume be measured? Is lung volume perception impaired in hEDS patients? Is the breathing control impaired during a cognitive task in hEDS patients? A device was developed to assess the accuracy of lung volume perception in patients with hEDS and matched control subjects.

The Standardized Pressure Injury Prevention Protocol (SPIPP) Checklist 2.0: Content validation.

Background: Pressure injury prevention is complex, and rates continue to rise. Checklists reduce human error, improve adherence and standardization with complex processes, focus attention on evidence-based practices derived from clinical practice guidelines and are arranged in a systematic manner to manage the entirety of a patient's risk for preventable outcomes. The original Standardized Pressure Injury Prevention Protocol was created to provide a checklist of pressure injury prevention measures but needed revision and validation.

Use of quality improvement methodology to improve care of women with hypertensive disease in pregnancy and haemorrhage in Yemen (low-income, high-insecurity setting).

This safety improvement project used quality improvement methods in a Comprehensive Emergency Obstetric and Newborn Care facility in Yemen, managed by an international humanitarian non-governmental organisation. It is responsible for about 6500 deliveries per annum. Following a local review of maternal deaths and serious incidents in 2020-2021, care for women with severe hypertensive disease in pregnancy and postpartum haemorrhage were highlighted as potential areas for improvement.

Enhanced photo-reactivity of polyanthracene in the VIS region.

The wavelength-dependent photo-reactivity of polyanthracene was explored upon UV-C and VIS light irradiation. The material was prepared via one-pot chemical oxidation route using FeCl3 as oxidizing agent. A decrease in surface hydrophobicity of a polyanthracene-coated poly(methylmethacrylate) substrate from 109.

Ventilatory Dysfunction in Parkinson's Disease.

In contrast to some other neurodegenerative diseases, little is known about ventilatory dysfunction in Parkinson's disease (PD). To assess the spectrum of ventilation disorders in PD, we searched for and reviewed studies of dyspnea, lung volumes, respiratory muscle function, sleep breathing disorders and the response to hypoxemia in PD. Among the studies, we identified some limitations: (i) small study populations (mainly composed of patients with advanced PD), (ii) the absence of long-term follow-up and (iii) the absence of functional evaluations under "off-drug" conditions.
