Two electrophoretic forms of erythrocytic carbonic anhydrase were found to be controlled by one autosomal locus with two codominant alleles, CAf and CA8. The gene frequencies for the CAf and CA8 alleles were found to be.15 and.85, respectively, in a sample of 53 mice from Middlesex County, New Jersey. The observed genotypic frequencies indicated that the population was in Hardy-Weinberg equilibrium.
A survey of a representative population sample was carried out to evaluate the prevalence and control of hypertension in Middlesex County, Ontario. Of the 3067 subjects selected 2735 completed the initial interview. If the diastolic blood pressure was greater than 89 mm Hg in three readings, up to two further visits were made. The prevalence rate of hypertension in the sample was estimated to be 115/1000. Only 5.1% of the hypertensive subjects were unaware of their condition, and 5.4% were aware but not receiving treatment. In 16.9% the hypertension was treated but uncontrolled, while in 72.6% it was treated and controlled. The prevalence rate was significantly higher in the older subjects (p < 0.0001). Control was better in the women and the older subjects. The results indicate that physicians in Middlesex County are detecting and treating most patients with hypertension; screening programs are thus not needed. Control of hypertension could be further improved by determining why the condition in those receiving treatment is not being controlled.
Scouting soybeans in Virginia is economically feasible with existing labor and insect treatment costs, present insect treatment practices, and at work efficiencies obtained in 2 years of study. In 1972, 36 fields averaging 23.9 acres were scouted for 4 weeks in Middlesex County at a cost of 7.2¢/acre/week. In 1973, 32 fields averaging 27.0 acres were scouted for 6 weeks in Virginia Beach at a cost of 5.5¢/acre/week. The percentage of insect control costs spent before insect populations reached levels at which Virginia Polytechnic Institute and State University recommends control was 87.2% in Middlesex County and 89.7% in Virginia Beach. Elimination of unnecessary control costs would have yielded net savings per dollar of outlay equal to $4.54 in 1972 and $3.13 in 1973.

The John O. McKellar was a ship that belonged to the Scott Misener fleet. The first ship named after McKellar was launched on Januaray 25, 1929, from Wallsend, England, and was bound for Sault St. Marie, Ontario. This ship became part of the Colonial Steamship Company in 1950, and in 1952 was renamed the J.G. Irwin when construction of a new John O. McKellar was completed.
John Oscar McKellar was born on June 28, 1878 in Lobo Township, Middlesex County, west of London, Ont. He worked as a marine engineer, and became acquainted with Robert Scott Misener when the two were shipmates serving with the Algoma central fleet. In 1919, the two men joined forces to run a shipping company. Together, they purchased the wooden steamer "Simon Langell", and worked together on the ship for the next three years. Throughout his career with Misener's company, John McKellar served as Chief Engineer, then Marine Superintendent, and finally Secretary-Treasurer. He died on September 19, 1951.; Consists of four certificates for the ship John O. McKellar. One is a Certificate of Class, Lloyd's Register of Shipping, issued January 15, 1954. The second is a Certificate for Machinery, Lloyd's Register of Shipping, also issued on January 15, 1954. The third is a Certificate of British Registry...
Aim: The aim of this study was to: 1) investigate the geographic distribution of six pregnancy complications associated with future maternal cardiovascular disease risk in the province of Ontario and 2) to identify regions where women are likely to benefit from post-partum cardiovascular disease screening, based on the development of complications during pregnancy.
Rationale: Cardiovascular disease is the leading cause of death in Canadian women. Pregnancy has been likened to a cardiovascular stress test and provides an early opportunity to assess a female’s lifetime risk of cardiovascular disease.
Methods: This study was a retrospective analysis of data collected for the Niday Perinatal Database, provided by the Better Outcomes Registry & Network. Crude and age-standardized cumulative incidences of six pregnancy complications, and one or more pregnancy complications, were calculated for each Public Health Unit area in Ontario. The cumulative incidence of one or more pregnancy complications for women with no previous history of cardiovascular disease or traditional cardiovascular risk factors was calculated at the Public Health Unit and census subdivision area levels. Spatial statistics were applied to locate statistically significant clusters of high cumulative incidence.
Results: Crude and age-standardized cumulative incidences of each pregnancy complication and one or more pregnancy complications varied across Public Health Unit areas in Ontario. The crude cumulative incidence of one or more complications ranged from 74 to 224 cases per 1000 pregnancies. The spatial analysis identified one statistically significant cluster of high cumulative incidence at the Public Health Unit area level...
OBJECTIVE: To determine physicians' attitudes toward prescribing acetylsalicylic acid (ASA), physicians' own use of ASA and the prevalence of ASA use in the community following the trials of ASA for primary prevention of coronary heart disease. DESIGN: Random sample surveys of physicians and the general public by mail and telephone respectively and a mail survey of a selected panel of expert cardiologists and neurologists. SETTING: London, Ont., and surrounding Middlesex County. PARTICIPANTS: A total of 210 physicians (77% of eligible subjects), including family practitioners and most types of specialists, with an active medical licence and 666 English-speaking people (75% of eligible subjects) aged 18 years or more living in a household with active, listed telephone service. MAIN OUTCOME MEASURE: Long-term ASA use (at least 80 mg on alternate days for 4 or more consecutive weeks) for the treatment of atherosclerosis. MAIN RESULTS: Sampled physicians and experts agreed that long-term ASA therapy was indicated in patients with unstable angina, a transient ischemic episode or recent myocardial infarction but not for primary prevention in healthy middle-aged men and women at low risk for ischemic vascular disease. Both groups were uncertain about the role of ASA in primary prevention in asymptomatic people with risk factors for atherosclerosis. Nine (16%) of the 55 male physicians aged 50 years or more took ASA routinely for primary prevention. In the community survey almost all those who used ASA routinely were 50 years or older. The proportions of men and women in this age group who used ASA routinely for any reason were 19% (95% confidence limits [CLs] 11 and 28) and 14% (95% CLs 8 and 19) respectively; the proportions of men and women who used ASA routinely and apparently for primary prevention were 8% and 1% respectively. A total of 43% (95% CLs 30 and 57) of those with apparent ischemic vascular disease took ASA routinely. Medically unsupervised long-term ASA use for primary or secondary prevention of ischemic vascular disease was uncommon (reported by 2% of those who used the drug routinely). CONCLUSIONS: Physicians generally agree on a role for long-term ASA therapy in the secondary prevention of ischemic vascular disease. However...
The dominance of Jamaican sprinters in international meets remains largely unexplained. Proposed explanations include demographics and favorable physiological characteristics. The aim of this study was to analyze the demographic characteristics of world class Jamaican sprinters. Questionnaires administered to 120 members of the Jamaican national team and 125 controls elicited information on place of birth, language, ethnicity, and distance and method of travel to school. Athletes were divided into three groups based on athletic disciplines: sprint (s: 100–400 m; n = 80), jump and throw (j/t: jump and throw; n = 25) and, middle distance (md: 800–3000 m; n = 15). Frequency differences between groups were assessed using chi-square tests. Regional or county distribution of sprint differed from that of middle distance (P < 0.001) but not from that of jump and throw athletes (P = 0.24) and that of controls (P = 0.59). Sprint athletes predominately originated from the Surrey county (s = 46%, j/t = 37%, md = 17, C = 53%), whilst middle distance athletes exhibited excess from the Middlesex county (md = 60%). The language distribution of all groups showed uniformity with a predominance of English. A higher proportion of middle distance and jump and throw athletes walked to school (md = 80%...
This article describes the results of an evaluation of Home Care Services, conducted by a patient questionnaire in Middlesex County. At the beginning, a brief description of Home Care Services sponsored by the Ontario Department of Health is provided. Home Care services previously have been known to help reduce the cost of medical services and increase the comprehensiveness of care for individual patients by transferring care to their home setting when applicable. All patients discharged between May 1, 1972 and June 30, 1972 were mailed the questionnaire. Information returned was analysed and results are discussed in the article. Our main objective was to evaluate the consumer's response to these services. Results were favorable indicating a strong acceptance of this form of community health service. It is hoped that this high degree of patient acceptance would encourage physicians to make greater use of this existing community service. Several minor criticisms were received and will hopefully help improve the quality of service provided in the future.
