The validation of heart rate variability in individuals with spinal cord injury

The current classification system for spinal cord injury (SCI) considers only somatic information and neglects autonomic damage after injiuy. Heart rate variability (HRV) has the potential to be a valuable measure of cardiac autonomic control after (SCI). Five individuals with tetraplegia and four able-bodied controls underwent 1 min continuous ECG recordings during rest, after Metoprolol administration (max dose=3x5mg) and after Atropine administration (0.02mg/kg) in both supine and 40° head-up tilt. After Metoprolol administration there was a 61.8% decrease in the LF:HF ratio in the SCI participants suggesting that the LF:HF ratio is a reflection of cardiac sympathetic outflow. After Atropine administration there was a 99.1% decrease in the HF power in the SCI participants suggesting that HF power is highly representative of cardiac parasympathetic outflow. There were no significant differences between the SCI and able-bodied participants. Thus, HRV measures are a valid index of cardiac autonomic control after SCI.

Drawing, St. Catharines House on February 26, 1849

A drawing done on paper 50cm x 45cm and mounted in a frame under glass. This is a drawing of a meeting held at the St. Catharines House on February 26, 1849. The drawing was done from memory by W. Osborn who has signed the picture on one of the pillars on the right hand side of the picture. The caption under the picture reads "Act 1st Scene 1st". There is some dialogue, "Woodruff - 'He says gentlemen, my son holds an office under Government, of 400 pounds per year - he forgot to tell you, he sold his constituents at Cornwall' - Macdonald 'You're a liar'". The artist portrays a fight breaking out and lists the characters as Boyd , Rykert, Hobdon, Foley, The Sheriff, Woodruff, J.W.O. Clarke, McDonald, Lamb, Hamilton and Hathaway. There are some very slight wrinkles and tears in the drawing. They do not affect the drawing. [Rolland MacDonald (1810-1881) represented Cornwall in the Legislative Assembly of the Province of Canada from 1844-1846. He was called to the bar in 1832 and set up practice in St. Catharines. The quote on the drawing concerns the constituents at Cornwall. This meeting was covered in reports in the St. Catharines Journal on: March 1, March 8, march 15 and march 22, 1849. There is also an excerpt in William Hamilton Merritt's diary noting the riot and the sketch by Osborn].

Letter - E.C. Schmon to Arthur A. Schmon, Monday Afternoon

The letter reads:" Dearest, How do you like this little surprise party? It is the latest way of sewing for the Red Cross - You remember I told you I was to meet Maud at two o'clock this afternoon, and we were going down to make surgical dressings? Well, thru a little misunderstanding about our meeting place, we missed each other; so I returned home. Mother thought I looked tired and insisted upon my taking a nap. I cam up to my room, and for an hour I've been trying to sleep, but "thought"(???) has prevented it. Artie dear, I have such an awful attack of the blues and while I was lying there trying to fight it, and also wishing that I knew your address - for I felt so much like writing to you, the thought came to me, that I could send a letter to you thru Chaunce, if I knew his company number. Hence - ensued a little chat with Mrs. Leake on the phone, and receiving the desired information, rushed to my desk, and - thus endeth the little tale. You are just about reaching Washington now, and I bet you are tired after that dreadfully monotonous trip. Take good care of yourself my "___"(?) Good luck, and lots of other wishes. Lovingly "Me". P.S. Write real, real soon and thank Chaunce for playing postman. L.

Health-related quality of life among patients attending cardiovascular rehabilitation

Purpose: f i rst , an investigation of baseline differences in Health-Related Quality of l i fe (HRQOl) among adhere and non-adhere patients of Phase III cardiac rehabilitation (CR) was examined. Second, among patients who adhered to the program, effectiveness of t reatment based on HRQOl was evaluated. Methods: Data was collected by the Brock University Heart Institute. Participants completed a questionnaire battery at baseline and again at six months i f they were still a client. Results: The physical dimension of HRQOl differed at baseline between the adhere and non-adhere groups. for everyone point increase in physical HRQOl scores there was an associated 1.06 times greater likelihood that an individual would adhere to the program. Second, in those who adhered to the program for six months, physical HRQOl scores improved 3.18 points. Conclusions: Phase III CR significant improves HRQOl in patients suffering f rom cardiovascular disease.

Self-Esteem and Mastery in Maintenance Cardiac Rehabilitation

Background: CVD is the second leading cause of death in Canada. Mastery and self-esteem are psychosocial factors, suggested to be emerging risk factors for CVD. Purpose: The purpose of the study was two-fold; first to establish whether mastery and self-esteem predicted adherence to maintenance CR; and second, whether mastery and self-esteem improved after a 6-month maintenance CR program. Methods: Data were collected at the Brock University Heart Institute. The study involved a sample of 98 participants. At intake to the program and 6-month follow-up, participants completed a questionnaire battery which included the Rosenberg Self-Esteem Scale and the Pearlin-Schooler Mastery Scale. Results: Mastery and self-esteem scores did not alter the likelihood of adherence to the CR program. Mastery and self-esteem did significantly improve after 6-months of CR amongst participants with the lowest exercise capacity. Conclusion: Maintenance CR does improve mastery and self-esteem amongst those with diminished exercise capacity.
