Q1 (12 points) In the paper “Is intestinal biopsy always needed for diagnosis of celiac disease” (Scoglio et al, Am Jour. of Gastroenterology, 2003), Figure 1 (below) describes a study of 181 patients undergoing biopsy for suspected celiac disease, 134 of whom were confirmed as celiac disease and 47 confirmed as not having celiac disease.

The following 2X2 table summarises the outcome of 75 amputations that he performed, where carbolic acid was used in 40 of these operations: Patient Survived Carbolic Acid Yes No Total Yes 34 6 40 No 19 16 35 Total 53 22 75 Grand Total (b) Compute the expected frequencies if there is no association between carbolic acid and survival and write these frequencies in parentheses in the cells of the table (3 points) (c) Conduct a significance test to see if there is a relationship between carbolic acid and survival: i) What Chi Square value do you get? __________ (3 points) ii) Provide an interval for the p-value using the tables on last page (____< p <_____) (2 points) iii) What do you conclude? ______________________________________(2 point) Q3. (10 points) A study was conducted in Uganda to estimate how delay in taking an infant to clinic affected the risk of them having symptoms that were consistent with both malaria and pneumonia (overlapping symptoms). Infants were categorised by age (1 = Up to 1 year, 2 = 1 to 2 years, 3 = Above 2 years). Stata gave the following output: . tab overlap agecat | agecat overlap | 1 2 3 | Total -----------+---------------------------------+---------- 0 | 1,031 555 363 | 1,949 1 | 649 283 142 | 1,074 -----------+---------------------------------+---------- Total | 1,680 838 505 | 3,023 . tabodds overlap agecat,or --------------------------------------------------------------------------- agecat | Odds Ratio chi2 P>chi2 [95% Conf.

Explain. (2points) (e) Is there evidence of a trend with age: if not, explain why; if yes, explain the trend in words. (2 points) 4 Biostatistics 1 Exam – Part 2, October 2014 Reference number: Q4 (12 points) In the paper “Breast cancer incidence, case-fatality and breast cancer mortality in Danish women using hormone replacement therapy – a prospective observational study” (Int. Journal of Epi, 2005), Stahlberg et al report the number of breast cancer cases among HRT users and non-users in the Danish Nurse Cohort. From the information presented in the first two columns of Table 1at the bottom of this page, complete the following table: (a) Complete the following table: (3 points) HRT use Breast cancer Non-cases Total cases never past current (b) Calculate the crude OR of breast cancer among the current HRT-users, with the never-users as the reference group.

The score in the first column, which ranges from 0 to 4, is the number of “yes” answers to four questions regarding sunbathing. (a) Calculate the crude RR for exposure groups 1-2, using the non-exposed (group 0) as reference.

  • Epidemic Models
    Chapter 9 Epidemic Models 9.1 Introduction to Epidemic Models Communicable diseases such as measles, influenza, and tuberculosis are a fact of life. We will be concerned with both epidemics, which are sudden outbreaks of a disease, and endemic situations, in which a disease is always present. The AIDS epidemic, the recent SARS epidemic, recurring influenza pandemics, and outbursts of diseases such as the Ebola virus are events of concern and interest to many peo- ple. The prevalence and effects of many diseases in less-developed countries are probably not as well known but may be of even more importance. Every year mil- lions, of people die of measles, respiratory infections, diarrhea, and other diseases that are easily treated and not considered dangerous in the Western world. Diseases such as malaria, typhus, cholera, schistosomiasis, and sleeping sickness are endemic in many parts of the world. The effects of high disease mortality on mean life span and of disease debilitation and mortality on the economy in afflicted countries are considerable. We give a brief introduction to the modeling of epidemics; more thorough de- scriptions may be found in such references as [Anderson & May (1991), Diekmann & Heesterbeek (2000)]. This chapter will describe models for epidemics, and the next chapter will deal with models for endemic situations, but we begin with some general ideas about disease transmission. The idea of invisible living creatures as agents of disease goes back at least to the writings of Aristotle (384 BC–322 BC). It developed as a theory in the sixteenth century. The existence of microorganisms was demonstrated by van Leeuwenhoek (1632–1723) with the aid of the first microscopes.

Rosser Matthews Professional Writing Program English Department 1220 Tawes Hall University of Maryland College Park, MD, USA +1 (301) 405-3762 [email protected] Abstract The history of biostatistics could be viewed as an ongoing dialectic between continuity and change. Although statistical methods are used in current clinical studies, there is still ambivalence towards its application when medical practitioners treat individual patients. This article illustrates this dialectic by highlighting selected historical episodes and methodological innovations – such as debates about inoculation and blood - letting, as well as how randomisation was introduced into clinical trial design. These historical episodes are a catalyst to consider assistance of non-practitioners of medicine such as statisticians and medical writers.

  • Joseph Lister
    JOSEPH LISTER By W. W. CH~PMAN, MONTREAL O-NIGHT is the fourteenth Convocation of our College, and Sir Ewen Maclean and myself are to say something to you. My own share of the honour and the Tobligation is to take the form of a Presidential Address, and you will agree that this is a serious undertaking. May I profess at once that I have been animated and encouraged to this task by the words of my predecessor in office, Rudolph Matas, of New Orleans. The admirable address of last year on "The Miasions and Ideals of the American College of Surgeons," has been to me, as to you all, a genuine help and inspiration; his well-timed message represents for the College, not only a prophecy but a fulfillment. A college of surgeons, if it means anything, is really a post-graduate school, a school in which we are enrolled during our. working life. As Fellows of this school, we enjoy many advantages, but we also incur a large responsibility. It is true that there is no definite academic staff, but what is much better, we teach one another; teach both by precept and example, the science and the art of surgery. And our curriculum comprises much more than this. We provide a common tribunal be- fore which new methods of surgical practice may be adjudged; we promote and encourage research; and we are earnestly concerned with the character and repu- tation of our Fellows. In a word, by attendance at this school, we are stimulated and encouraged to greater usefulness, more completely to find ourselves.

  • A Brief History of Law and Medicine 1
    CHAPTER A BRIEF HISTORY OF LAW AND MEDICINE 1 A page of history is worth a volume of logic. —Justice Oliver Wendell Holmes Jr. (New York Trust Co. v. Eisner, 256 U.S. 345, 349 [1921]) aw is ancient; medicine is a newborn. A bit of history will help put these Ltwo disciplines in perspective. What follows in this first chapter is historical synthesis, neither the product of primary research nor drawn from any one or even a few second- ary sources. It is, instead, a collection of harmonious facts, opinions, and sentiments drawn from varied perspectives, review of the literature, and the author’s personal experience. It is intended to give the reader a feel for what some might call the “crossroads” of law and medicine and to set the stage for a thoughtful overview of the law and healthcare administration. PART 1: THE HISTORY OF LAW After reading part 1 of this chapter, you will • understand that law comes from four basic sources, • know that no one branch of government is meant to be more powerful than another, • understand the legal citation system and certain key terms, and • be familiar with basic aspects of legal procedure. It is reasonable to assume that laws—rules for human interaction—have existed in some form since the first sentient beings roamed the earth. The oldest known written laws were proclaimed nearly four millennia ago by King Hammurabi of Babylon. They were inscribed on an eight-foot-tall black stela (stone pillar), lost for centuries but rediscovered in 1901 (see exhibit 1.1).
