Begin your search for scientific articles at the USQ Library website, specifically the PubMed database and/or Web of Science.
Topic(100 students MAX for each):
1. Septicaemia and antibiotics

Structure and components of the assignment:
Students will work individually to prepare an original essay on their chosen topic. The essay must be no longer than 1500 words (with a +10% leeway – you may submit a report that is more than 10% under the word limit, but this may be too brief and you will not be addressing the requirements).
In addition to the text and general information, figures and illustrations can be very important tools to convey complex information to your audience. You are welcome – and encouraged – to utilise appropriate illustrations to support your text. Just remember that your text must refer to your figures/illustrations, and any figures or illustrations must also be appropriately referenced.
What to include in your essay:
Your essay should include (but is not limited to):
• A summary/abstract (250 words maximum that does not count towards the 1500 word limit of the essay itself) that succinctly summarises the essays content.
o Your summary/abstract should follow the format of: introduction, summary of the main points/discussion in your essay, including the normal physiology, pathophysiology, and pharmacology, and then finish with a short conclusion.
o NOTE: references are not included with this
• An introduction and brief overview of the normal physiology and homeostasis of the system that is relevant to your chosen topic (Note that a thesis statement is NOT required)
• The pathophysiology and the mechanisms leading to the disease/disorder
• The pharmacology related to the treatment of the disease/disorder
o This must also include at least one specific drug example that addresses:
? Drug naming (chemical, generic, and proprietary)
? Mechanism of action (pharmacodynamics)
? Pharmacokinetics
? Route of administration
? Indications, contraindications, precautions and side effects
• You should also consider any other important aspects that may be relevant to your topic, for example:
o Are there any important drug interactions (other medications, natural products, etc) that patients should be aware of?
o Are there any lifestyle, exercise, therapy, or other physical considerations that are relevant? (for example, is the age of the patient a factor? BMI? Comorbidities? Polypharmacy? etc)
• The relevance of the disorder and pharmacology to clinical practice must also be clear
o This may be in any relevant context, but ideally your field of study (nursing, sports exercise, etc)
o For example, consider how you would apply your knowledge of the topic to your field in a clinical setting. How would this improve how you operate? How will this affect the clinical outcomes? How will this knowledge help you provide patient centred care? etc
• Conclusions
Important note: A key element of this assessment is the pharmacology. Alternate therapies, or different types of pharmacology, may be relevant for the disease/disorder that you are presenting, but if you do not present the pharmacology that is part of your specific topic you will not be addressing this part of the criteria and will lose marks.

Writing the summary/abstract:
You will need to write and submit a short (250 word) summary with your essay. This should succinctly summarise the essay’s content. It should follow the format of: introduction, summary of the main points/discussion (including the normal physiology, pathophysiology, and pharmacology) and finish with a short conclusion.
You will have the opportunity to engage with the Smarthinking team via the USQ library to get some early feedback on this element of your assessment. Please refer to the information on the related StudyDesk page. While this is not mandatory, the feedback that you can obtain from this process will be of particular help as you structure your main essay. Taking advantage of this will help you achieve the best possible mark for this assessment.
Your Smarthinking submission needs to completed by Wednesday 16th August. Submitting this on time is important to allow sufficient time for the Smarthinking tutors to provide feedback on your academic writing, so that this can assist you to improve your work on this assignment.
With this component of your assessment, please just note that references and in-text citations do not need to be included. Your references will be included with your full essay.
Finding information
You may draw your information from a variety of resources, but you should focus on current, up-to-date, research and the current state-of-knowledge. A good guide is to select a minimum of five recent and relevant journal publications on your topic and cover these in your essay (primary peer-reviewed research articles published in the past 5 years are what we are looking for).
All of your information sources should be referenced appropriately, and you should aim to avoid resources that may be unreliable or out-of-date (websites, news outlets, and similar, should be avoided).
Your references and in-text citations should be included within your essay, these do not need to be included with the summary/abstract. All references and in-text citations should be in the required reference format (Harvard AGPS or APA). References and in-text citations do NOT contribute to your word limit.
Textbooks can be a good resource for some established information and concepts, and these can be very useful during your initial investigations. However, you should then source the key information for your essay from evidence-based and peer-reviewed sources. Textbooks may be referenced in addition to these, but you should ensure that you are using journal publications as much as possible.
• You should aim for a minimum of 5 primary journal articles for your essay
• These are the type of publications that are required to address the references criteria (ie, not textbooks!)
Begin your search for scientific articles at the USQ Library website, specifically the PubMed database and/or Web of Science.
Referencing:
Referencing your information sources is an important part of this assessment. A reference list must be included with your essay (and this does NOT count towards the word limit).
The reference style will be:
• APA (https://www.usq.edu.au/library/referencing/apa-referencing-guide)
? You may choose to use either format, but you should only use the one format and must use it consistently

Selection of topics:
The topic selection activity will open on StudyDesk from 9:00am on Monday 17th July. This will remain open until it closes on 16th August.
You MUST have selected your topic before the activity closes. Any student who has not chosen a topic once the activity closes will be randomly assigned to one (students will be notified of their designated topic via an email to their USQ student email address).
Please note that each topic is also capped and only 70 students will be able to select each topic on a first- come first-served basis. So, if there is one particular topic that you are interested in, please ensure that you enter your selection as early as possible so that you don’t miss out!
When you are selecting your topic, make sure that you note the specific details. For example, if you choose a topic of “Diabetes mellitus (type 2) and sulfonylureas”, but you then prepare your essay on type 1 diabetes, or base it on insulin therapy, you will lose marks or receive a zero mark for the related criteria.

Septicaemia and antibiotics” based on our discussion:
Sepsis, also known as septicaemia or blood poisoning, is a serious medical condition characterized by the body’s extreme response to infection (National Institute of General Medical Sciences, 2020). It occurs when an infection you already have, like pneumonia, or a skin infection, spreads into the bloodstream and triggers a chain reaction throughout the body. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and even death (Center for Disease Control and Prevention, 2020). This paper will examine the pathophysiology of sepsis, common causative organisms and their antibiotic treatments, as well as ongoing challenges in managing this complex syndrome.
Pathophysiology of Sepsis
Sepsis occurs when bacteria or other microbes enter the bloodstream and trigger a system-wide inflammatory response (Mayo Clinic, 2021). In a healthy individual, inflammation helps fight infections by increasing blood flow to infected areas and activating the immune system. However, in sepsis this response becomes dysregulated and causes widespread inflammation throughout the body instead of localized inflammation at the original site of infection (Singer et al., 2016). As a result, sepsis can cause blood vessels to leak fluid, leading to low blood pressure and organ dysfunction. The dysregulated immune response also triggers blood clotting abnormalities that can obstruct small blood vessels and impair oxygen delivery to organs (National Institute of General Medical Sciences, 2020).
Common Causative Organisms and Treatments
Some of the most frequent causes of sepsis include Streptococcus pneumoniae, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa bacteria (Center for Disease Control and Prevention, 2020). S. pneumoniae is a leading cause of community-acquired pneumonia and meningitis, and first-line treatments include penicillins and cephalosporins (Bewick et al., 2019). Methicillin-resistant S. aureus (MRSA) is a major challenge in healthcare settings, treated with vancomycin or linezolid. E. coli is a common cause of urinary tract and bloodstream infections, treated with piperacillin-tazobactam or carbapenems. Multidrug resistant strains of K. pneumoniae and P. aeruginosa present difficulties, often requiring newer agents like ceftazidime-avobenzone or polymyxins (Livermore, 2012).
Challenges in Diagnosis and Treatment
Early diagnosis of sepsis remains problematic, as symptoms can mimic many other conditions in its early stages (Center for Disease Control and Prevention, 2020). This delay in recognition is a key factor in the high mortality rates associated with sepsis. Additionally, increasing antibiotic resistance has reduced treatment options for multidrug resistant organisms causing sepsis. This has led to more aggressive infection control measures and a renewed focus on developing novel antibiotics (WHO, 2017). Alternative strategies to bolster the immune system, like intravenous immunoglobulin and monoclonal antibodies, also show promise as adjunctive therapies for severe sepsis (The Lancet Infectious Diseases, 2018).
Conclusion
In summary, sepsis is a serious medical complication arising from the body’s maladaptive response to infection. Timely use of appropriate antibiotics against the causative organisms remains the primary treatment strategy. However, ongoing challenges include resistance, diagnosis, and a lack of new antimicrobial options. Further research into adjunctive immunotherapies and rapid diagnostics may help address some of these issues and improve outcomes in sepsis. Overall, as one of the leading causes of death worldwide, reducing the global burden of this syndrome remains an important public health priority.
