    1. Urgent treatment for neoplasm consists of (1) cautious use of intravenous diuretics and (2) mediastinal irradiation, starting within 24 hours, with a treatment plan designed to give a high daily dose of radiation but a short total course of therapy to rapidly shrink the local tumor. Intensive radiation therapy combined with chemotherapy will palliate the process in up to 90% of patients. In patients with a subacute presentation, radiation therapy alone usually suffices. Chemotherapy is added if lymphoma or small-cell carcinoma is diagnosed

      endovascular stenting emerging as first-line therapy for rapid symptom relief, while definitive treatment targets the underlying cause

      Glucocorticoids (dexamethasone 4 mg every 6 hours) are commonly prescribed but lack robust supporting data; they may be more beneficial in lymphoma or thymoma and as prophylaxis against radiation-induced edema. [2-4] Importantly, SVC syndrome is no longer considered a medical emergency except in rare cases with life-threatening cerebral edema, laryngeal edema, or altered mental status. When thrombosis is present, catheter-directed thrombolysis or aspiration thrombectomy should be performed within 2-5 days of symptom onset before thrombus organization occurs. [3] The role of long-term anticoagulation after stenting remains unclear, though it is standard when significant thrombosis is present The American College of Chest Physicians recommends obtaining histologic diagnosis before treatment in suspected lung cancer cases, as stenting does not interfere with tissue diagnosis. [2] For small cell lung cancer (SCLC), chemotherapy alone is recommended as first-line treatment given rapid response rates. [2] For non-small cell lung cancer (NSCLC), radiation therapy and/or stent insertion are recommended, with response rates of 59% for chemotherapy and 63% for radiation therapy. [2] Patients with chemotherapy- or radiation-refractory disease should receive vascular stents For device-related thrombosis (catheters, pacemakers), catheter removal should be considered in conjunction with anticoagulation. [4] Endovascular therapy is first-line for device-related obstruction, while surgical bypass may be preferred for mediastinal fibrosis. [7] Both approaches show good mid-term patency, though secondary interventions are common (approximately 27-28%

    1. Results for individual PALB2 variants were normalized relative to WT-PALB2 and the p.Tyr551ter (p.Y551X) truncating variant on a 1:5 scale with the fold change in GFP-positive cells for WT set at 5.0 and fold change GFP-positive cells for p.Y551X set at 1.0. The p.L24S (c.71T>C), p.L35P (c.104T>C), p.I944N (c.2831T>A), and p.L1070P (c.3209T>C) variants and all protein-truncating frame-shift and deletion variants tested were deficient in HDR activity, with normalized fold change <2.0 (approximately 40% activity) (Fig. 1a).

    1. Most Suspected Brugada Syndrome Variants Had (Partial) Loss of Function

      AssayResult: 10.2

      AssayResultAssertion: Abnormal

      ReplicateCount: 12

      StandardErrorMean: 3.4

      Comment: This variant had partial loss of function of peak current (10-50% of wildtype), therefore it was considered abnormal (in vitro features consistent with Brugada Syndrome Type 1). (Personal communication: A. Glazer)

    1. The honorable member has taken occasion to find fault with the clause of the resolutions which provides that the lieutenant-governors shall be appointed by the Central Government, and sees in it great danger, especially to Lower Canada. Mr. SPEAKER, I should very much like to know what protection the population of the different provinces derive from the fact that the governors of the British North American Provinces are sent out to us from England. Under the existing system, our governor is responsible neither to the people nor to the House ; he depends entirely upon the English Government, to which he is responsible. Under the system proposed the lieutenant-governors will be appointed by the Central Government, to which they will necessarily be responsible for their actions. And in that Government we shall have more than one vote ; we shall be represented in it by our ministers, who will be there to cause every encroachment or arbitrary act which the lieutenant-governor may allow himself to commit, to be condemned.
