Bright ideas to market your department

Nobody can do everything discussed in this article. Choose several ideas and try them. Increase your profile by letting more people in the hospital know who you are, what you do, when you do it, and how you do it. Get noticed and develop a reputation as the "go to" department. It will be worth the effort and increase your stature within the hospital. It may also help you get more staff and assume additional duties. Most of all, it will increase the respect of your department, and promote a more smoothly operating asset management system.     

Claude Bernard Distinguished Lecture. Becoming a truly helpful teacher: considerably more challenging, and potentially more fun, than merely doing business as usual

Few medical faculty members are adequately prepared for their instructional responsibilities. Our educational traditions were established before we had research-based understandings of the teaching-learning process and before brain research began informing our understandings of how humans achieve lasting learning. Yet, there are several advantages you may have. If your expertise is at one of the frontiers of human biology, your teaching can be inherently fascinating to aspiring health professionals. If your work has implications for human health, you have another potential basis for engaging future clinicians. And, thanks to Claude Bernard's influence, you likely are "process oriented," a necessary mindset for being an effective teacher. There are also challenges you may face. Your medical students will mostly become clinicians. Unless you can help them see connections between your offerings and their future work, you may not capture and sustain their interest. To be effective, teachers, like clinicians, need to be interactive, make on-the-spot decisions, and be "emotional literate." If you aren't comfortable with these demands, you may have work to do toward becoming a truly helpful teacher. Program changes may be needed. Might your program need to change 1) from being adversarial and controlling to being supportive and trust based or 2) from mainly dispensing information to mainly asking and inviting questions? In conclusion, making changes toward becoming a truly helpful teacher can bring benefits to your students while increasing your sense of satisfaction and fulfillment as a teacher. If you choose to change, be gentle with yourself, as you should be when expecting your students to make important changes.     

A patient's guide to choosing unconventional therapies

Unconventional therapies (UTs) are therapies not usually provided by Canadian physicians or other conventionally trained health care providers. Examples of common UTs available in Canada are herbal preparations, reflexology, acupuncture and traditional Chinese medicine. UTs may be used along with conventional therapies (complementary) or instead of conventional therapies (alternative). Surveys have shown that many Canadians use UTs, usually as complementary therapies, for a wide range of diseases and conditions. Reliable information about UTs is often difficult to find. Your doctor may be unable to give you specific advice or recommendations, since UTs are often not in a physician''s area of expertise. However, he or she will usually be able to provide some general advice and help supervise your progress. For your own health and safety, it is important to keep your doctor informed of the choices you make. This document is intended to (a) provide you with questions to consider when making your treatment choices, (b) help you find information about UTs, (c) help you decide whether a specific UT is right for you, and (d) provide tips to help you evaluate the information you find.     

How to safely maintain equipment where hazardous materials may lurk

The best protection is preparation. Assess any equipment/device that requires repair or maintenance for potential contamination or source of injury, such as sharp edges. Know where your protective apparel is located and use it. Review decontamination procedures and keep disinfectants available. Know your employee report of injury program and seek medical care whenever you have concerns regarding potential injury or exposure. Know your policies and procedures and where to find them if you need further information. Your infection control staff should be available 24 hours a day. The standard personal protective equipment that your employer is required to make available to you should include gloves, masks, eye protection, and gowns. In addition, if you are expected to enter a negative pressure room while a patient is in Airborne Precautions, you must be properly fit tested with an N95 respirator prior to entering the room. This respirator is very similar to a normal mask, but is able to filter out particles such as the TB bacterium. Infection control boils down to 2 commandments: 1. Wash your hands! 2. Use your head/common sense: If it looks soiled--clean it. If you have concerns--ask for clarification. If you think you have been exposed--seek medical assistance.     

Rungs on the ladder: developing a career structure for European researchers

When you are at the bottom of the career ladder in the life sciences it's often hard to see how high you can go or where it might lead you. In Europe, the academic ladder is missing at least one essential rung, and young researchers need better training to step out in new directions.     

Interpretation of diagnostic data: 3. How to do it with a simple table (part B).

The following guidelines are useful if you want to "do it with a simple table" (Table IV): First, identify the sensitivity and specificity of the sign, symptom or diagnostic test you plan to use. Many are already in the literature, and subspecialists should either know them for their field or be able to track them down for you. Depending on whether you are considering a sign, a symptom or a diagnostic laboratory test, you will want to track down a clinical subspecialist, a radiologist, a pathologist and so on. Start your table with a total of 1000 patients, as shown in location (a + b + c + d) of panel A. Using the information you have about the patient before you apply the diagnostic test, estimate the patient''s pretest likelihood (prevalence or prior probability) of the target disorder -- let''s say 10%. Take this proportion of the total (100) and place it in location (a + c); the remaining 900 patients go in location (b + d) (panel B). Multiply (a + c) (100) by the sensitivity of the diagnostic test (let''s say 83%) and place the result (83) in cell a and the difference (17) in cell c; similarly, multiply (b + d) (900) by the specificity of the diagnostic test (let''s say 91%) and place the result (819) in cell d and the difference (81) in cell b (panel C). If (a + b) and (c + d) do not add up to 1000, you will know you have made a mistake. You can now calculate the positive predictive value, a/(a + b), and the negative predictive value, d/(c + d), as shown in panel D. You have now reached a level of understanding a fair bit beyond the rule-in/rule-out strategy discussed in part 1 of our series. Furthermore, you can already do more than most clinicians, so you may want to stop here, at least for a while. On the other hand, you may want to go further and learn how to handle slightly more complex tables with multiple cut-off points. In the next article you will find more powerful ways to take advantage of the degree of positivity and negativity of diagnostic test results.     

Finding autophagy

To tell the truth, I find it difficult to work when flying, or even when sitting in an airport for an extended period of time. So, typically I take along a book to read. And when I truly cannot concentrate, for example when a flight is considerably delayed, I have even been known to resort to word puzzles. Depending on the type, they do not require much attention (that is, you can pick up right where you left off after you glance at the flight status screen for the twentieth or so time, even though you know nothing has changed), or effort (although you need to use a pen or pencil, not a keyboard), but nonetheless they can keep your mind somewhat occupied. I even rationalize doing them based on the assumption that they are sharpening my observational/pattern-finding skills. One type of word puzzle that is particularly mindless, but for that very reason I still enjoy in the above circumstances, is a word search; you are given a grid with letters and/or numbers, and a list of “hidden” terms, and you circle them within the grid, crossing them off the list as you go along. I do admit that the categories of terms used in the typical word searches can become rather mundane (breeds of dog, types of food, words that are followed by “stone,” words associated with a famous movie star, words from a particular television show, etc.). Therefore, on one of my last seminar trips I decided to generate my own word search, using the category of autophagy.     

Transition from academia to industry: a personal account

A career in industry has become a widely accepted alternative for those of us trained in medicine and/or science who have traditionally focused on careers in academia. Like any career decision, consideration of a position in industry should include asking yourself a series of fundamental questions. A few of the key questions should include: 1) What kind of work environment do you find most enjoyable? (e.g., patient care setting, basic research lab, team-oriented setting); 2) What are you focused on accomplishing in your career? (basic research discoveries, contributions to clinical medicine, compensation); 3) Are you team oriented in your interactions or are you more of an individual contributor? A successful career in any endeavor, including industry, starts with a careful and honest examination of what you are best suited for and inspired to do.

A Tale of Mother and Daughter

Loving science and nature and being a scientist can be very different, yet the two are so intertwined in a scientist''s life that you will certainly experience both aspects. This essay presents my perspective on how, as one who loves science and nature, I came to fall in love with centrosome behavior in stem cells and how I came to run a lab as a scientist. When I started, there was a big gap between my love for science and my experience as a scientist. I filled this gap by learning a “laid-back confidence.”Before the beauty of cell biology (or whatever you love), who you are (i.e., your age, gender, or race) is immaterial. Yet history shows that the ease with which you can pursue science is influenced by who you are. This has certainly been my experience. The key is to find a way to fill in the gap between who you are and what you are (i.e., a scientist), a goal in which we must all support each other. It is my hope that this essay will convey something helpful to those who are at early stages of their career and might be encountering obstacles because of who they are.     

Human voice perception

We are all voice experts. First and foremost, we can produce and understand speech, and this makes us a unique species. But in addition to speech perception, we routinely extract from voices a wealth of socially-relevant information in what constitutes a more primitive, and probably more universal, non-linguistic mode of communication. Consider the following example: you are sitting in a plane, and you can hear a conversation in a foreign language in the row behind you. You do not see the speakers' faces, and you cannot understand the speech content because you do not know the language. Yet, an amazing amount of information is available to you. You can evaluate the physical characteristics of the different protagonists, including their gender, approximate age and size, and associate an identity to the different voices. You can form a good idea of the different speaker's mood and affective state, as well as more subtle cues as the perceived attractiveness or dominance of the protagonists. In brief, you can form a fairly detailed picture of the type of social interaction unfolding, which a brief glance backwards can on the occasion help refine - sometimes surprisingly so. What are the acoustical cues that carry these different types of vocal information? How does our brain process and analyse this information? Here we briefly review an emerging field and the main tools used in voice perception research.     

Finding autophagy: It’s a question of how you look at it

To tell the truth, I find it difficult to work when flying, or even when sitting in an airport for an extended period of time. So, typically I take along a book to read. And when I truly cannot concentrate, for example when a flight is considerably delayed, I have even been known to resort to word puzzles.

Perceptually guided action: a step in the right direction

To walk to a target you need to know where it is. A recent study provides new insight into how the brain ensures you don't head off in the wrong direction.     

Move into hospital sector another sign of complementary medicine's growing popularity

Growing demand has led some Canadian hospitals to offer alternative therapies to patients, even though many physicians still question their efficacy. Anita Elash visited Toronto''s Sunnybrook Health Science Centre, where staff physicians have been debating the issue. One physician said hospitals have no choice but to offer the treatments. "If you believe in the primacy of patients making their own decisions and you believe in the fundamental of informed consent, you cannot deny them access to this treatment."     

Explain Bioinformatics to Your Grandmother!

What are you working on? You have certainly been asked that question many times, whether it be at a Saturday night party, during a discussion with your neighbors, or at a family gathering. Communicating with a lay audience about scientific subjects and making them attractive is a difficult task. But difficult or not, you will have to do it for many years, not only with your family and friends, but also with your colleagues and collaborators. So, better learn now! Although not usually taught, the ability to explain your work to others is an essential skill in science, where communication plays a key role. Using some examples of the French Regional Student Group activities, we discuss here (i) why it is important to have such communication skills, (ii) how you can get involved in these activities by using existing resources or working with people who have previous experience, and (iii) what you get out of this amazing experience. We aim to motivate you and provide you with tips and ideas to get involved in promoting scientific activities while getting all the benefits.     

Marine connectivity: timing is everything

Marine populations are connected through planktonic larvae that are dispersed at the whim of currents. But, living together does not mean dispersing together: connectivity depends not just on where you breed, but also on when you breed.     

Advance directives, autonomy and unintended death

This Paper argues that Living wills are typically nebulous and confused documents that do not effectively enable you to determine your future treatment. Worse, signing a living will can end your life in ways you never intended, long before you are either incompetent or terminally ill. This danger is compounded by the fact that those who implement living wills are often themselves dangerously confused, so that, for example, they cannot be relied upon to distinguish living wills from DNR orders. In addition, the Paper argues that advance directives concerning resuscitation are often so confused that they end the lives of healthy, alert people who have not suffered cardiac or pulmonary arrest. Finally, the paper argues that advance directives establishing durable power of attorney for health care often preserve the chief dangers of living wills. Suggestions are offered as to how you can most effectively direct your future treatment without endangering your life.     

Archeology and the First Americans

The land! don't you feel it? Doesn't it make you want to go out and lift dead Indians tenderly from their graves, to steal from them—as if it must be clinging even to their corpses—some authenticity.     

Location,location, location? No. Catalog number

Once you start to read this Editor’s Corner, you might wonder why I have devoted an entire article, albeit a short one, to this topic. Let me assure you there are reasons. First, I want to announce a new policy for the journal that will affect all research papers. Starting with all papers that are not currently in press, we will no longer be asking for geographical locations of research companies that follow the listing of a reagent. In Materials and Methods the authors typically refer to a reagent and then list the company and its location parenthetically. For example, “…p-nitrophenyl phosphate (Sigma-Aldrich, St. Louis, MO).” Instead, we will require catalog numbers. The reason is that it is now quite easy to find a company using the internet, and in fact you rarely need to know the location because it is rare that you would send a written order. On the other hand, knowing the name of the reagent is not always sufficient to narrow down the precise item. For example, if you search for “p-nitrophenyl phosphate” at the Sigma-Aldrich site, you get seven primary choices and it is not at all obvious which one to choose. When my lab uses p-nitrophenyl phosphate for the Pho8?60 assay, we use item N9389, which narrows it down to a precise reagent. Thus, we will start requiring papers to write “…p-nitrophenyl phosphate (Sigma-Aldrich, N9389).

Second, I think this is actually a useful change, and one that many journals will start to institute once they see it being done here. The old style of listing the city and state is a relic that is no longer relevant. Furthermore, it is not even clear in the current global marketplace if this is particularly helpful. For example, if I am ordering an item from Roche Applied Science, why would anyone care where it is coming from? It is highly unlikely that a researcher in Germany or Japan is going to order from Roche Applied Science that happens to be based in Indianapolis, IN when there are much closer sites in Mannheim, Germany and Tokyo, Japan. So, do not be surprised when you start to see more and more journals adopting this approach, and remember that you saw it here first. Autophagy—the cutting edge.     

Ten simple rules for finding and selecting R packages

R is an increasingly preferred software environment for data analytics and statistical computing among scientists and practitioners. Packages markedly extend R’s utility and ameliorate inefficient solutions to data science problems. We outline 10 simple rules for finding relevant packages and determining which package is best for your desired use. We begin in Rule 1 with tips on how to consider your purpose, which will guide your search to follow, where, in Rule 2, you’ll learn best practices for finding and collecting options. Rules 3 and 4 will help you navigate packages’ profiles and explore the extent of their online resources, so that you can be confident in the quality of the package you choose and assured that you’ll be able to access support. In Rules 5 and 6, you’ll become familiar with how the R Community evaluates packages and learn how to assess the popularity and utility of packages for yourself. Rules 7 and 8 will teach you how to investigate and track package development processes, so you can further evaluate their merit. We end in Rules 9 and 10 with more hands-on approaches, which involve digging into package code.
