Article Abstract
Pilot Project #1--the identification and characterization of human histone H4 proteoforms by top-down MS--is the first project launched by the Consortium for Top-Down Proteomics (CTDP) to refine and validate top-down MS. Within the initial results from seven participating laboratories, all reported the probability-based identification of human histone H4 (UniProt accession P62805) with expectation values ranging from 10(-13) to 10(-105). Regarding characterization, a total of 74 proteoforms were reported, with 21 done so unambiguously; one new PTM, K79ac, was identified. Inter-laboratory comparison reveals aspects of the results that are consistent, such as the localization of individual PTMs and binary combinations, while other aspects are more variable, such as the accurate characterization of low-abundance proteoforms harboring >2 PTMs. An open-access tool and discussion of proteoform scoring are included, along with a description of general challenges that lie ahead including improved proteoform separations prior to mass spectrometric analysis, better instrumentation performance, and software development.
Background: An endoscopic screening program following successful weaning from prolonged mechanical ventilation maintained through endotracheal tube (ET; ) may be justified to assess the upper (laryngotracheal) airway in children who may not always be symptomatic for intubation-related complications.
Objectives: To evaluate effects of prolonged intubation in children through endoscopic screening of the laryngotracheal airway.
Methods: In this cross-sectional pilot project, children (2 months-12 years) successfully extubated following prolonged intubation were selected, irrespective of having symptoms, for a 1-time flexible nasolaryngoscopy at third to sixth month post-extubation (follow-up window).
Background: Sheep scab, caused by the highly infectious mite, is considered to be endemic in Northern Ireland, although little investigation has been reported. A pilot project was undertaken to engage farmers, confirm cases with diagnostic methods and identify specific barriers to control, with the aim of informing future control programmes.
Methods: Through farmers self-reporting suspected outbreaks, on-farm risk assessments and clinical investigations were carried out by the farm's veterinary surgeon, who utilised light microscopy and serological testing to diagnose scab.
Background: Given the close relationship that can exist between substance use health and mental health (SUHMH) concerns, the need for more integrated services and support has been identified. However, research on the effective integration of SUHMH services and their impact on outcomes of individuals accessing them remains limited. In particular, the unique outcomes of individuals facing significant structural inequities in the health care system, i.
Objective: To report the results and feasibility of a pilot expansion of the Toronto Tele-Retinal Screening Program in an elderly long-term care home.
Methods: Long term care patients with Type II diabetes mellitus (DM) were screened between April 1, 2022, and July 1, 2022. Demographic and health data were collected through surveys.
To address the challenges posed by influenza, its associated complications, and economic burden, the World Health Organization recommends a vaccination rate exceeding 75 % for populations at elevated risk of severe diseases. Presently, vaccination rates in Germany severely lag behind. To augment these rates, pilot projects have been initiated, allowing community pharmacists to administer vaccines.
