RESUMO
OBJECTIVE: Dose de-escalation of adjuvant therapy (DART) in patients with HPV(+)OPSCC was investigated in two prospective Phase II and III clinical trials (MC1273 and MC1675). We report the 30-day morbidity and mortality associated with primary TORS resection in patients enrolled in these trials. MATERIALS AND METHODS: Patients with HPV(+)OPSCC, who underwent TORS resection between 2013 and 2020 were considered in this analysis. The severity of postoperative transoral bleeding was graded using both the Hinni Grade (HG) transoral surgery bleeding scale and the Common Terminology for Adverse Events (CTCAE) v5.0. Post-surgical complications within 30 days of surgery, as well as rates of tracheostomy, PEG and nasogastric tube placement. RESULTS: 219 patients were included. A total of 7 (3.2 %) patients had a tracheostomy placed at the time of surgery, and all were decannulated within 26 days (median: 5, range: 2-26). There were 33 (15.1 %) returns to the emergency department (ED) with 10 (4.6 %) patients requiring readmission. Using the HG scale, 10 (4.6 %) patients experienced ≥ Grade 3 bleeding with no Grade 5 or 6 bleeds. In contrast, using the CTCAE scale, 15 patients (6.8 %) experienced ≥ Grade 3 bleeding with no Grade 5 bleeds. There was one post-operative death in a patient withdrawn from the trial, and no deaths related to hemorrhage. CONCLUSION AND RELEVANCE: TORS for HPV(+)OPSCC in carefully selected patients at a high volume center was associated with low morbidity and mortality.

Six treatments of eastern Kansas tallgrass prairie--native prairie, hayed, mowed, grazed, burned and untreated--were studied to examine the biophysical effects of land management practices on grasslands. On each treatment, measurements of plant biomass, leaf area index, plant cover, leaf moisture and soil moisture were collected. In addition, measurements were taken of the Normalized Difference Vegetation Index (NDVI), which is derived from spectral reflectance measurements. Measurements were taken in mid-June, mid-July and late summer of 1990 and 1991. Multivariate analysis of variance was used to determine whether there were differences in the set of variables among treatments and years. Follow-up tests included univariate t-tests to determine which variables were contributing to any significant difference. Results showed a significant difference (p < 0.0005) among treatments in the composite of parameters during each of the months sampled. In most treatment types, there was a significant difference between years within each month. The univariate tests showed, however, that only some variables, primarily soil moisture, were contributing to this difference. We conclude that biomass and % plant cover show the best potential to serve as longterm indicators of grassland condition as they generally were sensitive to effects of different land management practices but not to yearly change in weather conditions. NDVI was insensitive to precipitation differences between years in July for most treatments, but was not in the native prairie. Choice of sampling time is important for these parameters to serve effectively as indicators.

Compared migraine headache suffers and matched normal controls on the Zung Depression Inventory, Eysenck Personality Inventory, Spielberger Trait Anxiety Inventory, Taylor Manifest Anxiety Scale and the Health Locus of Control. In addition Ss viewed a film of a subincision ceremony and completed a post-film questionnaire. Migraineurs scored significantly higher than the controls on the TMAS, STAI and EPI Lie scale and rated the subincision film as significantly less unpleasant than did the controls. These results confirm earlier reports that migraineurs have higher levels of trait anxiety than normals and support the traditional description of migraineurs as inhibiting the expression of their feelings.

To assess the potential of antihypertensive drugs for interference with somatic growth and sexual development in hypertensive children, the effect of clonidine therapy on various endocrine, cardiovascular, and neuromuscular functions has been examined in five male adolescents with idiopathic hypertension. In studies done before and at the end of 4 weeks of twice-daily clonidine therapy, in an average daily dose of 0.31 mg, no significant effects were noted in the secretory patterns of growth hormone, luteinizing hormone, follicle-stimulating hormone, prolactin, cortisol, aldosterone, or testosterone, measured in blood obtained every 20 minutes for 24 hours. In blood obtained while the patients were supine and then erect, plasma renin activity and norepinephrine levels were significantly lowered after clonidine therapy. Cardiovascular responses to dynamic exercise were little altered beyond a 17% decrease in maximal oxygen consumption. The performance of fine motor skills was minimally altered. These data provide preliminary evidence that clonidine, an antihypertensive drug that affects the adrenergic nervous system, may not interfere with normal growth and maturation in adolescent males.
