Black individuals exhibit increased blood pressure (BP) responses to sympathetic stimulation that are associated with an increased risk of hypertension (HTN). We tested the hypothesis that α1 -adrenergic blockade inhibits the increased BP response during and after 45-min stress in young normotensive Black adults, which may be mediated, in part, by dampened vasoconstriction and decreased renal sodium retention. Utilizing a double-masked randomized, crossover study design, 51 normotensive Black adults (31 ± 8 yr) were treated with either a placebo or 1 mg/day of prazosin for 1 week. On the final day of each treatment, hemodynamic measures and urinary sodium excretion (UNaV) were collected before (Rest), during (Stress) and after (Recovery) 45 min of mental stress induced via a competitive video game task. During the Stress period, diastolic BP and total peripheral resistance (TPR) were significantly lower with prazosin compared to placebo (p less then .05 for both). Similarly, we observed lower systolic BP, diastolic BP, and TPR during the Recovery period with prazosin versus placebo (p less then .05 for both). There was no effect of prazosin on stress-associated UNaV. The change in systolic BP from Rest to Recovery was positively associated with the change in TPR with both treatments (p less then .05 for both). In summary, prazosin treatment dampened BP reactivity to 45-min mental stress and lowered post-stress BP over the recovery period, which was linked to reduce TPR in young normotensive Black adults. These results suggest that α1 -adrenergic receptor activity may contribute to BP responses and delayed BP recovery to prolonged mental stress through increased vasoconstriction in Black adults.Hypoxia-inducible factor 1α (HIF-1α) is a transcription factor mediating adaptive responses to hypoxia and ischemia. Our previous work showed that HIF-1α is increased in muscle sensory nerves of rats with peripheral artery disease (PAD) induced by femoral artery occlusion. The present study was further to examine the role played by HIF-1α in regulating the response of arterial blood pressure (BP) to the activation of muscle afferent nerve during static muscle contraction in rats with femoral artery occlusion. A rat model of femoral artery ligation was used to study PAD in this study. Western blot analysis was employed to examine the protein levels of HIF-1α in the dorsal root ganglion (DRG) tissues. Chroman 1 mw BAY87, a synthesized compound with the characteristics of highly potent and specific suppressive effects on expression and activity of HIF-1α, was given into the arterial blood supply of the ischemic hindlimb muscles before the exercise pressor reflex was evoked by static muscle contraction. First, HIF-1α was increased in the DRG of occluded limbs (optical density 0.89 ± 0.13 in control versus 1.5 ± 0.05 in occlusion; p 0.05, n = 5 in each group). In addition, muscle contraction evoked a greater increase in BP in occluded rats. BAY87 attenuated the enhanced BP response in occluded rats to a greater degree than in control rats. Our data suggest that the inhibition of HIF-1α alleviates the exaggeration of the exercise pressor reflex in rats under ischemic circumstances of the hindlimbs in PAD induced by femoral artery occlusion. To assess the correlation of WHO histological classification and Masaoka-Koga staging system of thymic epithelial tumors (TETs) with prognosis. We retrospectively analyzed 83 patients with TETs in the Instituto Nacional de Enfermedades Neoplasicas between 1996 to 2018. We analyzed the clinical stages, histological types and treatment modalities and attempted to determine the impact on overall survival. The data was retrieved from clinical files and reviewed by a pathologist who reclassificated according to the 2004 WHO classification system. The staging was performed with the Masaoka-Koga staging system. Survival curves were constructed with Kaplan-Meir method. There was a total of 83 patients with a median age of 55 years old included in the study. The histological type corresponded to thymoma (T) in 63.8% (n = 53) and to thymic carcinoma (TC) in 36.1%. T were type A, AB, B1, B2 and B3 in 14.4%, 18%, 12%, 3.6%, 7.4% of cases, respectively. The proportion of advanced disease (Masaoka stage III-IV) was high (65%). With a median follow-up of 88.4 months, median overall survival (OS) was 81.6 months for T and 12.3 months for TC (P = 0.01). Univariate analysis showed that sex, histological type, clinical stage and surgery (P = 0.01) were significant independent prognostic factors. On multivariate analysis, histology type and Masaoka-Koga staging had an effect on survival. The results indicates a clear association between the WHO histological classification and Masaoka-Koga staging system with survival. We found a higher proportion of TETs with advanced disease at diagnosis. Further research are required and collaboration is important to foster knowledge focused on classification and treatment. SIGNIFICANT FINDINGS OF THE STUDY The WHO histological classification, the Masaoka-Koga system and surgery treatment were associated with overall survival. To determine prognosis factors in TETs.To determine prognosis factors in TETs. A successful academic interview has been reported as the most important factor contributing to ranking of candidates for residency. However, little published guidance exists to help a prospective oncologist or researcher give such an interview. The International Society of Paediatric Oncology (SIOP) Young Investigator (YI) Network and Children's Oncology Group (COG) YI group thus cosponsored a survey of senior investigators seeking their advice. An electronic survey covering aspects of the academic interview of both trainees and faculty were sent to all current/past mentors serving in the COG YI mentorship program and those registered as mentors in the SIOP YI mentorship program. The responses were quantitatively and qualitatively analyzed. The response rate was 43.7% (118/270) from 25 countries. Majority of United States (US) interviewers (86.8%) conducted interviews individually, while 74% of non-US interviewers conducted panel interviews or both types equally (P<.001). Majority of interviewers (83.
