Usability and outcomes of self-monitored surgical wound healing using a smartphone-based application by patients following neurosurgery.

Background: The Radboudumc developed a smartphone application (WondGezond) to collect surgical wound-healing information provided by the patient.

Aim: To evaluate usability and outcomes to assess its potential for early surgical site infection (SSI) detection.

Methods: Patients surgically treated for degenerative spinal disorders or carpal tunnel syndrome between August 2020 and February 2023 were enrolled one day post surgery and asked to download the app via a quick-response (QR) code.

Assessment of antimicrobial mismatches in empirical treatment in early PJI after aseptic revision arthroplasty.

Background: In early periprosthetic joint infection (PJI), 'debridement, antibiotics and implant retention' (DAIR) is a widely accepted form of treatment. Empirical antimicrobial treatment is started while culture results of tissue samples taken during debridement are pending.

Objectives: In this retrospective study we assessed the antimicrobial mismatch rate between empirical treatment and the susceptibility of the causative microorganisms of PJI after aseptic revision arthroplasty.

Phytochemical Characterization of Wild Hops ( ssp. ) Germplasm Resources From the Maritimes Region of Canada.

A survey was conducted in the Maritimes region of eastern Canada to measure the phytochemical diversity of prenylchalcone, soft resins (alpha & beta acids), and flavonol constituents from 30 unique wild-growing populations of hops ( L.). Based on cone chemometrics, the majority of accessions (63.

NMR characterization of novel pyranoanthocyanins derived from the pulp of Panax quinquefolius L. (North American ginseng).

Three major pigments (one natural and two derived) were determined to be present in the berry pulp of Panax quinquefolius L. (North American ginseng). The first was a simple anthocyanin (pelargonidin 3-O-lathyroside) along with two novel pyranoanthocyanins, structurally similar to those recently discovered in Staghorn sumac.

Comparison of the performance of IFA, CFA, and ELISA assays for the serodiagnosis of acute Q fever by quality assessment.

The indirect immunofluorescence assay (IFA) is considered the reference method for diagnosing Q fever, but serology is also performed by complement fixation assay (CFA) or enzyme-linked immunosorbent assay (ELISA). However, comparability between these assays is not clear, and therefore a quality assessment was performed. A total of 25 serum samples from negative controls, Q fever patients, and a serial diluted high-positive sample were analyzed in 10 Dutch laboratories.
