A COnsensus-based Standards for the selection of health Measurement INstruments systematic review of orthognathic patient-reported outcome measures.

INTRODUCTION: This systematic review aimed to identify and appraise the validity studies of patient-reported outcome measures (PROMs) reporting the outcomes of combined orthodontic-orthognathic surgery in treating dentofacial deformity. METHODS: The search strategy was conducted using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Systematic Review methodology. The following databases were searched for original studies outlining the development and/or validation of PROMs produced to measure the outcomes of combined orthognathic-orthodontic treatment: EMBASE, MEDLINE, PsycInfo and Scopus. Publications were limited to the English language. Eligibility criteria were applied when considering the studies. Primarily, the psychometric properties and quality of orthognathic-specific PROMs were investigated. Screening of eligible studies was conducted independently by 2 reviewers. Assessment of the methodological quality of the studies and data extraction was conducted by 1 reviewer and assisted by a second reviewer. The COSMIN methodology guided data extraction and analysis, which were divided into 3 stages-a synopsis of studies, evaluation of methodological quality, and summary of evidence. RESULTS: A total of 8695 papers were found; 12 studies met the criteria for inclusion. Regarding the COSMIN Checklist for Assessing Study Qualities, there was evidence that the Orthognathic Quality of Life Questionnaire was the most extensively tested orthognathic-specific PROM in the current literature. The reported evidence was incomplete, as not all psychometric properties had been reliably tested. CONCLUSIONS: Clinicians must use validated PROMs when analyzing patient-reported outcomes. The Orthognathic Quality of Life Questionnaire was shown to be the highest quality orthognathic-specific PROM in the literature but requires contemporary evaluation to suitably reflect the COSMIN guidance.

Plasma Membrane Fusion Is Specifically Impacted by the Molecular Structure of Membrane Sterols During Vegetative Development of Neurospora crassa.

Cell-to-cell fusion is crucial for the development and propagation of most eukaryotic organisms. Despite this importance, the molecular mechanisms mediating this process are only poorly understood in biological systems. In particular, the step of plasma membrane merger and the contributing proteins and physicochemical factors remain mostly unknown. Earlier studies provided the first evidence of a role of membrane sterols in cell-to-cell fusion. By characterizing different ergosterol biosynthesis mutants of the fungus Neurospora crassa, which accumulate different ergosterol precursors, we show that the structure of the sterol ring system specifically affects plasma membrane merger during the fusion of vegetative spore germlings. Genetic analyses pinpoint this defect to an event prior to engagement of the fusion machinery. Strikingly, this effect is not observed during sexual fusion, suggesting that the specific sterol precursors do not generally block membrane merger, but rather impair subcellular processes exclusively mediating fusion of vegetative cells. At a colony-wide level, the altered structure of the sterol ring system affects a subset of differentiation processes, including vegetative sporulation and steps before and after fertilization during sexual propagation. Together, these observations corroborate the notion that the accumulation of particular sterol precursors has very specific effects on defined cellular processes rather than nonspecifically disturbing membrane functioning. Given the phenotypic similarities of the ergosterol biosynthesis mutants of N. crassa during vegetative fusion and of Saccharomyces cerevisiae cells undergoing mating, our data support the idea that yeast mating is evolutionarily and mechanistically more closely related to vegetative than sexual fusion of filamentous fungi.

A Fresh Start or the Devil You Know? Examining Relationships Between Release Location Choices, Community Experiences, and Recidivism for High-Risk Parolees.

This study investigated the effects of residential relocation in a sample of 282 high-risk male offenders paroled from New Zealand prisons. Initially we compared those returning to their old neighborhoods (devil you know) and those released to a new location (fresh start). This second category was then further divided: those released to a new location voluntarily (fresh start-voluntary) versus those forced to start anew at the behest of the parole board that was releasing them (fresh start-duress). All three categories were then compared on the quality of their community experiences and recidivism. Results indicated that parolees returning by choice to either their old neighborhood or a new location each were reconvicted in the first year after release at approximately the same rate; however, parolees relocating to a new area at the direction of the parole board (under duress) were reconvicted at a higher rate than those in either of the voluntary location categories. Significant group differences in ratings of community life quality were few, but there were some indications that compared with those choosing to return to a familiar location, making a voluntary residential relocation may lead to better parole experiences, particularly in terms of avoiding criminal peers, and that making a residential relocation under duress may lead to poorer parole experiences than for those returning to a familiar location.
