Abstract
INTRODUCTION Quantitative measurement and analysis of glottic abduction is used to assess laryngeal function and success of interventions; however, the consistency of measurement over time has not been established. This study assesses the consistency of glottic abduction measurements across visits in healthy patients and anatomic factors impacting these measurements. METHODS Review of patients with two sequential flexible stroboscopic exams over seven months from 2019-2022. Images of maximal glottic abduction were captured and uploaded into and measured with ImageJ. Cadaver heads were used to assess the impact of visualization angles on glottic measurements with a monofilament inserted into the supraglottis of each cadaver as a point of reference. Comparisons were done with a paired T-test, T-test, or Mann-Whitney U test as appropriate. RESULTS Fifty-nine patients and twenty-six cadaveric exams were included. Absolute change in maximum glottic abduction angle (MGAA) was 6.90° (95% CI [5.36°, 8.42°]; p < 0.05). There were no significant differences in change in MGAA by gender or age. Twenty percent of patients had a change of at least 25% in their MGAA between visits. Absolute differences in glottic angle between nasal side for cadaveric measurements was 4.77 ± 4.59° (p < 0.005)-2.22° less than the change in MGAA seen over time (p = 0.185). CONCLUSION Maximal glottic abduction angles varied significantly between visits. Factors considered to be contributing to the differences include different viewing windows between examinations due to the position and angulation of the laryngoscope and changes in patient positioning, intra- and inter-rater variations in measurement, and patient effort. LEVEL OF EVIDENCE N/a Laryngoscope, 2024.

Abstract
OBJECTIVE This study aimed to determine the long-term outcomes of patients with chronic refractory cough (CRC) following treatment for cough suppression therapy (CST). Currently, there is a lack of objective data regarding the long-term outcome of behavioral treatment for CRC. METHODS From the charts of 106 adult patients diagnosed with CRC, 24 patients were identified as having long-term data at least 3 months post-CST in the form of otolaryngologic examination, Voice Handicap Index-10 (VHI-10), and Cough Severity Index (CSI) scores. Patients underwent otolaryngologic evaluation and completed the VHI-10 and CSI assessments during pretreatment, posttreatment, and long-term follow-up visits. Patients were also divided into two groups based on their number of comorbidities. RESULTS Twenty of the 24 patients had significant reduction in cough severity after completing CST (P < 0.001). A significant difference was also found in CSI scores from pretherapy to the long-term follow-up visits (P = 0.001). No significant difference was found in CSI scores from posttherapy to long-term follow-up visits (P = 0.93). No significant difference was found in VHI-10 scores over time (P = 0.83). No correlation was found between changes in cough and voice severity and number of comorbidities at the tested level. CONCLUSIONS Findings of no significant change in CRC over the long term compared to posttherapy measures suggest that patients were able to maintain improvement in cough over the long term despite various comorbidities. The current results suggest that CST represents a satisfactory approach to treating CRC and provides patients with an ongoing tool to maintain reduced cough severity. No significant correlations between number of comorbidities and mean CSI or VHI-10 scores were found over the long term.

Abstract
We have observed directional spontaneous emission of rhodamine 6G dye deposited on top of a silver grating and found that its angular distribution patterns were very different in TE and TM polarizations. The latter was related to the dispersion curves determined based on the polarized reflection spectra measured at multiple incidence angles. The most intriguing finding of this Letter was a resonance, which was coupled with TE-polarized light and determined the characteristic double-crescent patterns in the TE-polarized spontaneous emission. This observation, as well as nearly similar resonance observed in TM polarization, was tentatively explained in terms of leaky waveguide modes supported by a film of dye-doped polymer.

Abstract
We report the first branching-ratio measurement of the superallowed 0+→0+β transition from Ca38. The result, 0.7728(16), leads to an ft value of 3062.3(68) s with a relative precision of ±0.2%. This makes possible a high-precision comparison of the ft values for the mirror superallowed transitions, Ca38→38mK and K38m→Ar38, which sensitively tests the isospin symmetry-breaking corrections required to extract Vud, the up-down quark-mixing element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, from superallowed β decay. The result supports the corrections currently used and points the way to even tighter constraints on CKM unitarity.

Abstract
BACKGROUND AND AIMS Genome size is a function, and the product, of cell volume. As such it is contingent on ecological circumstance. The nature of 'this ecological circumstance' is, however, hotly debated. Here, we investigate for angiosperms whether stomatal size may be this 'missing link': the primary determinant of genome size. Stomata are crucial for photosynthesis and their size affects functional efficiency. METHODS Stomatal and leaf characteristics were measured for 1442 species from Argentina, Iran, Spain and the UK and, using PCA, some emergent ecological and taxonomic patterns identified. Subsequently, an assessment of the relationship between genome-size values obtained from the Plant DNA C-values database and measurements of stomatal size was carried out. KEY RESULTS Stomatal size is an ecologically important attribute. It varies with life-history (woody species < herbaceous species < vernal geophytes) and contributes to ecologically and physiologically important axes of leaf specialization. Moreover, it is positively correlated with genome size across a wide range of major taxa. CONCLUSIONS Stomatal size predicts genome size within angiosperms. Correlation is not, however, proof of causality and here our interpretation is hampered by unexpected deficiencies in the scientific literature. Firstly, there are discrepancies between our own observations and established ideas about the ecological significance of stomatal size; very large stomata, theoretically facilitating photosynthesis in deep shade, were, in this study (and in other studies), primarily associated with vernal geophytes of unshaded habitats. Secondly, the lower size limit at which stomata can function efficiently, and the ecological circumstances under which these minute stomata might occur, have not been satisfactorally resolved. Thus, our hypothesis, that the optimization of stomatal size for functional efficiency is a major ecological determinant of genome size, remains unproven.

Abstract
Between 1974 and 1989, a lateral closing wedge osteotomy was used to correct posttraumatic cubitus varus in 36 patients. In 35 (97%) of the patients, the deformity was corrected to within 5 degrees of the contralateral elbow, and the patient was satisfied with the result. There were no nerve palsies or infections. Of the nine patients treated before age six years, seven had a minimum 2-year follow-up (average 9 years), and there was no evidence of recurrent deformity. This technique allows good correction of deformity with minimal complications.

Abstract
STUDY OBJECTIVE To compare information contained in standard out-of-hospital trauma triage criteria and standard criteria plus advanced emergency medical technician (EMT) injury severity perception for determination of patient need for trauma center evaluation. DESIGN Prospective, observational cohort analysis of trauma triage by advanced EMTs. PARTICIPANTS Out-of-hospital, geographically stratified statewide sample of patients injured in Oregon. RESULTS Advanced EMTs provided patient information on demographics, physiologic parameters, injury anatomy and mechanism, premorbid conditions, EMT injury severity perception, and trauma system entry status. A four-point scale was used to grade the injury severity perception. Need for trauma center evaluation was defined as major surgery within 6 hours of hospital arrival, admission to the ICU, death in the hospital, or Injury Severity Scale score of 16 or more. The relative triage information gain with injury severity perception was assessed by use of logistic regression, tree-based models, and receiver operating characteristic (ROC) curves. Of 1,063 patients, 307 (28.9%) warranted trauma center evaluation. With logistic regression modeling, the following standard triage parameters were associated (P < .05) with the need for trauma center evaluation after inclusion of injury severity perception: systolic blood pressure less than 90 mm Hg, abnormal respiratory rate (less than 10 or more than 29), Glasgow Coma Scale score less than 13, penetrating injury (midthigh to head), two or more obvious proximal long-bone fractures, and fall of more than 20 feet. The two largest injury severity perception categories had the greatest odds ratios (20:1 and 167:1). ROC curve areas improved with injury severity perception (.88 versus .83 without; P < .0001). CONCLUSION Standard out-of-hospital triage criteria benefit from inclusion of advanced EMT injury severity perception information.

Abstract
STUDY OBJECTIVE To report intracity, regional trauma, geographic, and demographic factors affecting risk of major intentional versus nonintentional trauma. DESIGN One-year retrospective analysis of trauma-registry and census-tract databases. SETTING Urban trauma system with patient entry by emergency medical services personnel. PARTICIPANTS Major trauma cases grouped by presumed intent to injure. INTERVENTIONS We examined age- and sex-adjusted trauma rates for seven geographic intracity regions (comprising of 144 census tracts) to identify associations with population density, median household income, and race data. Rates and risk factors for intentional versus nonintentional trauma were compared. RESULTS Two hundred fifty-seven intentional and 575 nonintentional major trauma system cases were identified. Both intentional (relative risk [RR], 7.0; 95% CI, 5.1 to 9.7) and nonintentional (RR, 2.7; CI, 2.3 to 3.3) injury populations were predominately male. Intentional-trauma victims were disproportionately nonwhite (RR, 4.1; CI, 3.2 to 5.1). The 15- to 24-year-old (RR, 20.3; CI, 16.7 to 24.6) and 25- to 34-year-old (RR, 15.3; CI, 12.7 to 18.4) age groups were more likely to sustain intentional trauma than the 0- to 14-year-old age group. Regional differences in occurrence rates were most pronounced for intentional trauma; 52% of all intentional traumas occurred within a small area of 14 census tracts. Residents in low median income households were more commonly subject to intentional injury. CONCLUSION Different demographic features affect intentional and nonintentional major trauma in Portland, Oregon. These features can be used to guide emergency medical services planning and injury-prevention measures.

Abstract
To determine if out-of-hospital emergency medical services (EMS) time intervals are associated with unexpected survival and death in urban major trauma, a retrospective review was conducted of major trauma cases entered into an urban trauma system by an EMS system during a one-year period. Patients with unexpected death or unexpected survival were identified using TRISS methodology. The EMS response, on-scene time, transport time, and total EMS out-of-hospital time intervals were compared for the two groups using the unpaired t test (two-tailed analysis). Of 848 major trauma cases, there were 13 (1.5%) unexpected survivors and 20 (2.4%) unexpected deaths. Of those patients with complete EMS times, the mean out-of-hospital response time interval was significantly shorter for the unexpected survivors (3.5 +/- 1.2 minutes v 5.9 +/- 4.3 minutes; P = .04). The mean EMS on-scene time interval (7.8 +/- 4.1 minutes v 11.6 +/- 6.5 minutes; P = .06) and the mean transport time interval (9.5 +/- 4.4 minutes v 11.7 +/- 4.0 minutes; P = .17) also favored the unexpected survivor group. Overall, the total EMS time interval was significantly shorter for unexpected survivors (20.8 +/- 5.2 minutes v 29.3 +/- 12.4 minutes; P = .02). It was concluded that a short overall out-of-hospital time interval may positively affect patient survival in selected urban major trauma patients.

Abstract
Fifteen knees were treated with a surgical technique designed for recurrent patellar dislocations when associated with patella alta. The average number of patellar dislocations preoperatively was 12, and the determination of patella alta was made using the technique described by Insall and Salvati, which is a ratio of the length of the patellar tendon to the longest diagonal length of the patella. The normal value for this ratio is 1.02 plus or minus 20%. The average preoperative ratio in this study was 1.58 (range, 1.2-2.1), which changed to 1.08 (range, 0.99-1.14) by the time of follow-up examination. The surgical technique used involves transposing the patellar tendon insertion distally without any medialization or recessing and allows for good bone contact for healing, secure fixation, and immediate postoperative motion. There were no recurrences of patellar dislocation postoperatively and few complications. Only one patient complained of anterior knee pain in the follow-up period. This technique is thought to give good results when it is used specifically for recurrent patellar dislocations associated with patella alta.

Abstract
Supernatants from isolated trophoblast cell cultures (trophoblastic fluid) derived from first-trimester human placentas were assessed for immunoregulatory activity. Trophoblastic fluid at different days of culture consistently inhibited the blast transformation of allogenic lymphocytes. This suppressor effect had no apparent correlation with biosynthesis of human chorionic gonadotropin by trophoblast cells, since this hormone was secreted into the culture fluid only for the initial 3 days. However, the culture fluids of such purified trophoblast cells contained an immunosuppressive factor, pregnancy-associated plasma protein A, which was measurable throughout the culture period of 8 days. The presence of pregnancy-associated plasma protein A in significant amounts in trophoblastic fluid collected at daily intervals indicated a continuous secretion ability of pregnancy-associated plasma protein A by trophoblast cells in culture parallel to the suppressive immunoregulatory effect of the fluid. Such immunosuppressive effect was absent in the culture fluids of control BeWo malignant trophoblast cells; the BeWo cell culture fluids had markedly reduced levels of pregnancy-associated plasma protein A. The culture supernatant of normal trophoblast cells of placentas from first-trimester pregnancy activated in vitro the generation of a population of suppressor lymphocytes. This effect is generally considered responsible for immunologic tolerance. Therefore demonstration of immunosuppressive effects and the presence of relatively high levels of pregnancy-associated plasma protein A in trophoblastic fluid indicate that such proteins secreted by the trophoblast cells may be important in the local immunoregulatory processes of the fetal allograft.

Abstract
8-methoxypsoralen (8-MOP), activated upon exposure to long-wavelength ultraviolet radiation, is used therapeutically to treat the diseased blood cells of cutaneous T-cell lymphoma patients. The factors responsible for the efficacy of this therapy are reviewed. Primary among these are the plasma level of 8-MOP at the time of irradiation and the effective dose of UVA. 8-MOP plasma levels determined in a series of six patients demonstrated that the drug is absorbed at a highly variable rate (122 ng/ml +/- 67). A new liquid form of 8-MOP is absorbed with a modest increase in plasma levels (170 ng/ml) but with no improvement in the variability (+/- 163). An examination of the dose-response relationship between 8-MOP concentration and UVA dose indicated that properties such as 8-MOP photoadduct formation and PHA response are proportional to the combined doses of these two factors. A new molecular target for 8-MOP photomodification, cell membrane DNA, is described.
