Before you pick your essay title, you need to know your audience. Are you writing this for just your teacher, for your teacher and your peers, for your boss, your coworkers, for blog or magazine readers? Identifying your audience will help you pick the type of title that is right for your essay. Informative titles like "The Benefit of Owning a Cat vs. a Dog", for example, would be better for a classroom setting, while a creative title like "My Dog is Better than a Cat" would be better for a blog. An informative title should tell your reader exactly what you are comparing in your essay. List the subjects you want to compare so that you can make sure they are included in your title. You only need to include the broad topics or themes you want to compare, such as dogs and cats. Don't worry about putting individual points in your title. Those points will be addressed in the body of your essay. You may be comparing something to itself over time or space, like rock music in the 20th and 21st centuries, or Renaissance art in Italy and the Netherlands. If that's the case, list the subject you want to compare, and places or timeframes that you are using for your comparison. Some compare and contrast essays are meant to persuade readers toward a certain opinion, such as "Why Cats are Better than Dogs". Other essays aim for a more objective comparison of content or facts, like "The Benefits of Owning a Cat vs. a Dog". Consider whether the goal of your essay is just to compare, or to persuade through comparison. Persuasive essay titles might use words like "benefit," "better," "advantages," "should," "will," and other words that convey a sense that one subject has an advantage over the other. Informative titles might use words like "versus," "compared," or "difference". These words don't suggest that one subject is better or worse, they simply point out they are not the same. Once you know what you want to compare, how you want to compare them, and if an informative title is right for your essay, it's time to put it all together. Use your persuasive or informative words to link your subjects together. The end result should be a title that lets readers know what you want to compare and contrast, and how you plan on doing so in just a few words. If for example, you're comparing rock music across time, your title might be The Difference in Chord Progressions of 20th and 21st-century Rock Music.

Many colleges and universities offer traditional and online courses related to etymology. There will not be a broad array of related courses available, but there is likely to be one or two at most higher education institutions. The best place to look for classes related to etymology are in the Classics, English, and Linguistics departments. Keep in mind that you will have to be enrolled at a college or university in order to take a course through them. Most courses taken for credit will require you to be accepted as a student through a formal application process and to pay a tuition fee. No colleges or universities currently offer degrees specifically in etymology. However, many higher ed institutions do have Linguistics Departments that offer bachelor's, master's, and/or doctoral degrees. Getting a degree in Linguistics is the best preparation you can have for becoming a professional word historian. The QS World University Rankings publishes an annual list of the top international programs in Linguistics according to their strengths in research and reputation along with their student and faculty ratio and diversity. Study etymology in a hands-on way. There isn't too much call for professional etymologists these days. However, if you'd like to pursue a career in word history, the best way to go about it is to seek an editorial position with a quality dictionary, like the Oxford English Dictionary. Dictionaries require constant updates to word definitions and etymologies, which means they always need new editorial staff. Search for job openings at dictionaries that interest you. They could be anything from the Oxford English Dictionary to Dictionary.com.

To treat severe cases of dengue fever at a hospital, doctors will begin by introducing intravenous (IV) fluids and electrolytes (salts) into the patient's body. This treatment works to replace the fluids lost through vomiting or diarrhea. This step will only be taken if the patient is not able to take fluids orally (e.g., because of severe vomiting) or is in shock. Intravenous means "within a vein." In other words, liquid substances will be infused directly into one of the patient's veins via a syringe or intravenous catheter. The recommended first-line IV fluid is crystalloids (0.9% saline). Doctors will monitor the patient's fluid intake through IV due to newer guidelines recommending a more cautious intake of IV fluids than in the past. This is because overhydration can cause adverse effects, including intravascular fluid overload, or a flooding of the capillaries. For this reason, in most cases, doctors will administer fluid in increments, rather than a constant flow. In more advanced and severe cases cases of dengue, doctors may have to perform a transfusion to replace lost blood. This is often the required treatment for patients whose dengue has escalated to DHF. A transfusion can entail transfer of fresh blood into the patient's system or just platelets, which are parts of the blood that help the blood clot and are smaller than red or white blood cells. Corticosteroids are man-made drugs that closely resemble cortisol, a hormone produced naturally by your adrenal glands. These drugs work by decreasing inflammation and reducing the activity of the immune system. The effects of corticosteroids on dengue infection are still undergoing medical trials and are as yet inconclusive.
