These findings could be used by clinicians in developing rehabilitation programs to prevent further ankle sprains in patients with severe ankle joint laxity.

Our data suggest that severe ankle joint laxity affects rearfoot horizontal plane kinematics in individuals without perceived ankle instability performing a 45° side-cutting task. These findings could be used by clinicians in developing rehabilitation programs to prevent further ankle sprains in patients with severe ankle joint laxity.Climate change can have substantial impacts on nitrogen runoff, which is a major cause of eutrophication, harmful algal blooms, and hypoxia in freshwaters and coastal regions. We examined responses of nitrate loading to climate change in the Upper Mississippi River Basin (UMRB) with an enhanced Soil and Water Assessment Tool with physically based Freeze-Thaw cycle representation (SWAT-FT), as compared with the original SWAT model that employs an empirical equation. Driven by future climate projections from five General Circulation Models (GCMs) from 1960 to 2099 under the Representative Concentrations Pathways (RCP) 8.5 scenario, we analyzed changes in riverine nitrate loadings, as well as terrestrial surface and subsurface contributions of the UMRB in the 21st century relative to the baseline period of 1960-1999. By the end of the 21st century, the original SWAT model predicted about a 50% increase in riverine nitrate loadings which is nearly twice as much as that estimated by SWAT-FT (ca. 25%). Such a large difference in projected nitrate changes can potentially mislead mitigation strategies that aim to reduce nitrogen runoff from the UMRB. Further analysis shows that the difference between the original SWAT model and SWAT-FT led to substantial discrepancies in the spatial distribution of surface and subsurface nitrate loadings in the UMRB. In general, SWAT-FT predicted more nitrate leaching for northwestern parts of the UMRB which are more sensitive to freeze-thaw cycle, mainly because SWAT-FT simulated less frequent frozen soils. This study highlights the importance of using physically based freeze-thaw cycle representation in water quality modeling. Design of future nitrogen runoff reduction strategies should include careful assessment of effects that land management has on the freeze-thaw cycles to provide reliable projection of water quality under climate change.

To determine whether transoral rigid laryngeal endoscopy (TORLE) or transnasal flexible fiberoptic laryngoscopy (TNFFL) is more favorable for laryngeal endoscopic examination in the elderly population.

This randomized prospective study carried out in a tertiary reference center. learn more TORLE or TNFFL were performed to patients who were over 65years at their first visit according to randomization list. At their second visit, other method was performed. Patients' physiological parameters (Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and oxygen (O

) saturation before and immediately after laryngeal examination were recorded. Patients' pain-irritation, gag reflex, and dyspnea status were evaluated using visual analog scale after first and second endoscopic examinations. Further patient preferences for TORLE and TNFFL were recorded.

Of 96 patients included in the study, 69.8% (n=67) preferred TORLE while 30.2% (n=29) preferred TNFFL. Major factor influencing patient preferences was pain-irritation in TNFFL. Pain-irritation scores were significantly higher in TNFFL than those in TORLE (p<0.001). However, no significant difference was found between two methods with respect to gag reflex and dyspnea scores (p=0.194, p=0.327, respectively). In TORLE, there was no statistically significant difference between the values measured before and after examination in terms of SBP, DBP, HR, and O

saturation (p=0.641, p=0.134, p=0.119, p=0.414, respectively). However, in TNFFL, statistically significant decrease was observed after examination in HR and O

saturation (p<0.001, p<0.001, respectively).

TORLE is more suitable for laryngeal examination in elderly patients since it is more comfortable for patient and does not change physiological parameters.

Patients with COVID-19 who are intubated and require mechanical ventilation have been observed to have oropharyngeal bleeding necessitating otolaryngology intervention.

We report five cases of oropharyngeal hemorrhage in COVID-19 patients on mechanical ventilation requiring evaluation by otolaryngologists at George Washington University Hospital (GWUH) and Boston Medical Center (BMC) from March to April 2020. Institutional Review Board at both institutions exempted this study from informed consent because there were no identifiable patient characteristics, photographs, or imaging studies included.

All five patients were managed conservatively; four required packing with Kerlix gauze by an otolaryngologist. Two patients had the additional requirement of extracorporeal membrane oxygenation (ECMO) and associated anticoagulation. Three patients improved with oropharyngeal packing; two had persistent bleeding. Three patients expired. Endotracheal tubes were repositioned less frequently due to the COVID-19 pandemic.

Intubated patients with COVID-19 may have an increased risk of oropharyngeal hemorrhage. This may be due to anticoagulation, prolonged intubation, or decreased frequency of endotracheal tube repositioning. Otolaryngologists should wear appropriate PPE when managing this hemorrhagic complication.

Patients with suspected coronary artery disease who undergo stress SPECT myocardial perfusion imaging (MPI) and require pharmacologic stress are at substantially increased mortality risk compared to those who can exercise. However, the mechanisms underlying this increased risk are not well delineated. To test whether increased atherosclerotic burden accounts for this increased risk, we assessed the association between coronary artery calcium (CAC) scores and mortality risk among patients undergoing exercise versus pharmacologic SPECT MPI.

We assessed all-cause mortality in 2,151 patients, followed for 12.2±3.4 years, after undergoing stress-rest SPECT-MPI and CAC scanning within 3 months of each other. Patients were divided according to their mode of stress testing (exercise or pharmacologic). We further employed propensity analysis to create a subgroup of exercise and pharmacologic subgroups with comparable age, symptoms, and coronary risk factors.

Despite greater age and worse clinical profiles, pharmacologic and exercise patients had similar CAC scores.
