Inflammation, lines of defence and immunity titers

Two questions only, labelled in the format the sample specifies. Answering all of them thins each one and misses the instruction that is being graded alongside the content.

01

Choose two, and label which two you chose

Start with the instruction rather than the content. You select two of the listed questions and indicate which you have chosen using the format shown in the Discussion Forum Sample, which means the labelling is itself graded, and answering everything on the list is not diligence but a straightforward failure to follow the brief. Choose the pair you can answer with real specificity rather than simply taking the first two on the list, since depth is what a 250-word answer rewards. Each of the three has a distinct centre of gravity and rewards a different kind of answer. The diet and inflammation question is about mechanism: how diets high in refined sugars and processed foods promote a low-grade chronic inflammatory state through metabolic and microbiome pathways, and how that differs from the acute inflammatory response, which is protective and self-limiting. Getting that contrast explicit is most of the answer to the first question.

The lines of defence question needs the terminology exactly right, because it is easy to state loosely. The first line is the physical and chemical barrier — intact skin, mucous membranes, cilia, gastric acidity, normal flora. The second is the innate inflammatory and phagocytic response, non-specific and immediate. What interferes with them is concrete and clinically familiar: breaches from surgery, catheters and cannulae, malnutrition, corticosteroids, chemotherapy, uncontrolled diabetes and age at both extremes. The titers question is the most practical of the three and rewards precision: a titer is a quantitative measure of specific antibody in serum, and serological testing is used to infer immunity when vaccination records are unavailable — with the important caveat that a negative titer does not always mean absent immunity, since cellular memory can persist without detectable circulating antibody, which is why guidance differs by disease and why the answer cannot be a single rule.

Likely learning objectives

Inferred from the brief — check these against your own rubric.

  • 01
    Distinguish acute inflammation from chronic low-grade inflammation by mechanism.
  • 02
    State the first and second lines of defence precisely and what compromises each.
  • 03
    Explain serological titers and the limits of a negative result.

Review every instruction before using the planning guidance that follows.

Discussion Inflammation and autoimmune diseases Discussion: Inflammation and autoimmune diseases Select two of the following discussion questions for your discussion response. Indicate which questions you have chosen using the format displayed in the “Discussion Forum Sample.” Inflammation is a process that accompanies many different autoimmune disease processes. In addition, a diet that is high in sugars and processed foods can also cause inflammation. Discuss health risk factors related to dietary habits and inflammation. Explain the differences between the primary and secondary line of defense. What factors interfere with these mechanisms? How are these levels of immunity affected in a child, an elderly person, or a person with a chronic disease? Ms. Smith presents to her primary care provider (PCP) for a comprehensive medical exam. titers for various childhood diseases are included in the exam because she is not able to find her immunization records. What are “titers” and what type of testing is required to establish immunity? at least 250 words with reference no older than 5 years and intext citation.
Course-wide instructions that accompany this question

Important information for writing discussion questions and participation Hi Class, Please read through the following information on writing a Discussion question response and participation posts. Contact me if you have any questions. Important information on Writing a Discussion Question Your response needs to be a minimum of 150 words (not including your list of references) There needs to be at least TWO references with ONE being a peer reviewed professional journal article. Include in-text citations in your response Do not include quotes—instead summarize and paraphrase the information Follow APA-7th edition Points will be deducted if the above is not followed Participation –replies to your classmates or instructor Discussion Inflammation and autoimmune diseases A minimum of 6 responses per week, on at least 3 days of the week. Each response needs at least ONE reference with citations—best if it is a peer reviewed journal article Each response needs to be at least 75 words in length (does not include your list of references) Responses need to be substantive by bringing information to the discussion or further enhance the discussion. Responses of “I agree” or “great post” does not count for the word count. Follow APA 7th edition Points will be deducted if the above is not followed Remember to use and follow APA-7th edition for all weekly assignments, discussion questions, and participation points. Here are some helpful links Student paper example Citing Sources The Writing Center is a great resource Welcome to class Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to. I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

  2. 2.
    Use CDC serologic testing guidance for the titers answer, which specifies which diseases titers are used for.
  3. 3.
    Search for chronic low-grade inflammation reviews rather than general nutrition articles.
  4. 4.
    Check your text's terminology for lines of defence, since numbering conventions vary between sources.

Review before submission

Common mistakes

  • Answering all the questions instead of the two the brief asks for.
  • Omitting the labelling format, which is an explicit instruction.
  • Confusing the first and second lines of defence or blurring innate and adaptive immunity.
  • Treating a negative titer as proof of absent immunity.

Submission checklist

  • Have you answered exactly two questions and labelled them as the sample shows?
  • Is the acute versus chronic inflammation distinction explicit?
  • Are the lines of defence stated with correct components?
  • Are all references within five years?
