Focus Groups to Inform the Development of a Patient-Reported Outcome Measure (PROM) for Temporomandibular Joint Disorders (TMDs).

Background: Understanding symptoms of temporomandibular joint disorders (TMDs) can help doctors and patients document, monitor, and manage the disease and help researchers evaluate interventions. Patients with TMDs experience symptoms ranging from mild to severe, primarily in the head and neck region. This study describes findings from formative patient focus groups to capture, categorize, and prioritize symptoms of TMDs towards the development of a patient-reported outcome measure (PROM).

Patient-reported outcome measures for individuals with temporomandibular joint disorders: a systematic review and evaluation.

Objective: We used consensus-based, systematic protocols to evaluate the reliability and validity of patient-reported outcome measures (PROMs) for use in documenting treatment outcomes for temporomandibular disorders (TMDs).

Study Design: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a focused search of 5 literature databases resulting in a yield of 445 articles that qualified for full-text review. Our review identified 124 PROMs, from which we selected 19 directly related to symptoms of TMD including temporomandibular joint (TMJ) function.

Evolution for exogenous octanoic acid tolerance improves carboxylic acid production and membrane integrity.

Carboxylic acids are an attractive biorenewable chemical, but as with many biorenewables, their toxicity to microbial biocatalysts limits their fermentative production. While it is generally accepted that membrane damage is the main mechanism of fatty acid toxicity, previous metabolic engineering efforts that increased membrane integrity did not enable increased carboxylic acid production. Here we used an evolutionary approach to improve tolerance to exogenous octanoic acid, with the goal of learning design strategies from this evolved strain.

Transcriptomic analysis of carboxylic acid challenge in Escherichia coli: beyond membrane damage.

Carboxylic acids are an attractive biorenewable chemical. Enormous progress has been made in engineering microbes for production of these compounds though titers remain lower than desired. Here we used transcriptome analysis of Escherichia coli during exogenous challenge with octanoic acid (C8) at pH 7.
