1. A significant global health challenge remains HIV/AIDS, which is caused by the Human Immunodeficiency Virus (HIV). In order to combat the disease, it is crucial to understand its transmission, pathogenesis, clinical manifestations, treatment, and prevention (Centers for Disease Control and Prevention [CDC, 2021).
HIV primarily spreads through sexual contact, exposure to contaminated blood, and perinatal transmission (CDC, 2021). The virus targets CD4+ T cells, macrophages, and dendritic cells, leading to a progressive decline in the immune system’s function (Koyama et al., 2020). As the disease progresses, individuals may experience clinical manifestations such as flu-like symptoms, opportunistic infections, and malignancies. Further clinical manifestations of acute HIV infection include fever, headache, fatigue, arthralgia, vomiting, diarrhea, pharyngitis, rash, ulcers, and swollen glands. AIDS infection can manifest in the form of opportunistic infections, most commonly thrush, esophageal candida, Kaposi sarcoma, recurrent bacterial pneumonia, and disseminated or pulmonary tuberculosis.
HIV/AIDS is managed with antiretroviral therapy (ART), which suppresses viral replication, preserves immune function, and reduces transmission (CDC, 2021). ART consists of a combination of different classes of drugs, including nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase strand transfer inhibitors, and fusion inhibitors (CDC, 2021; Koyama et al., 2020). In addition, HIV/AIDS treatment generally consists of monitoring for increased CD4 levels, lowering the viral load with antiretroviral therapy, and treating opportunistic infections. When untreated, patients with HIV tend to develop AIDS within about 10 years, and once diagnosed with AIDS, if they do not receive treatment, they usually die within two years. In addition HIV prevention medications like pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis can be used to lower viral loads (Waymack & Sundareshan, 2021).
Prevention strategies are crucial to controlling the spread of HIV/AIDS. These include promoting safe sexual practices, ensuring the availability of clean needles for injection drug users, and implementing programs for early identification and treatment of HIV-infected individuals (CDC, 2021). Additionally, pre-exposure prophylaxis (PrEP) is recommended for individuals at high risk of acquiring HIV (CDC, 2021).
In conclusion, a comprehensive understanding of the transmission, pathogenesis, clinical manifestations, treatment, and prevention of HIV/AIDS is essential in addressing this global health issue. Efforts should focus on implementing effective prevention strategies, ensuring access to treatment, and promoting public awareness.

3. Discuss the transmission, pathogenesis, clinical manifestations, treatment, and prevention of HIV/AIDS.
Transmission: HIV/AIDS is transmitted through sexual intercourse, blood or blood products, IV drugs, and maternal-child transmission (2022). Some genetic factors influence the transmission of HIV such as polymorphism of the CXCR4 or CCR5 coreceptor molecules are less likely to become infected. Also, someone that is homozygous for the ?32 mutation of CCR5 coreceptor is immune to the virus (Rogers, 2023). Lastly, a person’s viral load of the source of the infection and the person’s effectiveness of immune function influence a person’s chance of transmission.
Pathogenesis: HIV first infects macrophages and dendritic cells which then travel to the lymph nodes to affect Th cells. As HIV begins to replicate, it enters the bloodstream and produces flu-like symptoms (Rogers, 2023). The more Th cells that become infected, the more HIV replicates. T cytotoxic (Tc) cells activate in order to kill cells that have been infected. The bone marrow produces more Th cells to replace the one being killed (Rogers, 2023). Eventually the bone marrow loses its capability of producing enough Th cells to replace those being killed off and HIV then advances to AIDS.
Clinical Manifestations: According to the Mayo Clinic, clinical manifestations can be broken down by the stages of HIV: primary infection, clinical latent infection, symptomatic HIV infection, and progression to AIDS (2022). During the primary infection a person will experience: fever. Headache, muscle aches and joint pain, rash, sore throat with painful mouth sores, swollen lymph glands on neck, diarrhea, weight loss, cough, and night sweats (2022). When the virus progresses to clinical latent infection, a person may have no symptoms or infections and can stay this way for many years if treatment with antiretroviral therapy is happening. Symptomatic HIV infection includes the above, plus oral yeast infections, shingles, and pneumonia get added to the list of symptoms. HIV has progressed to AIDS when the Th cells are less than 200 cells/ mm or when opportunistic infections or cancers occur (Rogers, 2023). Other manifestations include neurologic or metabolic complications, and lesions on tongue or mouth (Rogers, 2023).
Treatment: While there is no current cure for HIV, there are antiretroviral therapy (ART) medications that can help slow the progression. The use of multiple different drug classes is used to best treat the virus (Rogers, 2023).
Prevention: Prevention strategies include avoiding unprotected sex and needle sharing (Rogers, 2023). It is also important for those that are infected to take their medications as prescribed. Frequent testing can also help to prevent the spread of HIV. New advances have also shown pre and post-exposure prophylaxis in antiretroviral medication (Rogers, 2023).
4. For many, the most significant stand-out feature between quantitative and qualitative research is the numerical factor. Quantitative research focuses on measuring and quantifying data, while qualitative research focuses on gathering and interpreting non-numerical data such as from interviews, documents, and observations (Hoover, 2021). Table 4-2 from Tappen’s textbook demonstrates helpful compare/contrast descriptions between quantitative and qualitative research. Quantitative research is objective and demonstrates reliability and validity, while qualitative data is subjective and its purpose is to discover information (Tappen, 2016, table 4-2). Personally, I prefer quantitative research because for me the data is clearer because it is numerical and objective. With good quantitative research, one can make predictions about subsequent experiments. Depending on what topic is being researched one will need to decide between using quantitative or qualitative research. If the ultimate goal of the research is to test hypotheses or quantify data, then quantitative research would be more suited. On the other hand, qualitative research is helpful for topics where more in-depth research is sought after to provide more detailed information. For myself, quantitative research seems to be more mathematical, while qualitative research can be more philosophical.
5. One of the differences between quantitative and qualitative research is that quantitative includes numbers and qualitative does not (Tappen, 2015). The goal of quantitative research is to create proposals that can describe and predict certain situations that can be used to generalize other situations (Tappen, 2015). For example, if a hospital floor wanted to reduce the chance of patients falling, they could use data from quantitative research that showed the instance of it happening (Tappen, 2015). This data could show the different factors that have increased patient falls and could be used to hopefully decrease patient falls in that hospital floor (Tappen, 2015). Qualitative research is based on why or how something happened (Tappen, 2015). The data gathered in qualitative studies are usually non-numerical and are more subjective in nature rather than objective like in quantitative research (Tappen, 2015). I would choose to develop a research project that was quantitative if I wanted data that had reliability and validity (Tappen, 2015). I’d also choose quantitative if I wanted verification of a topic. I would choose to develop a research project that was qualitative if I wanted data that was trustworthy (Tappen, 2015). I’d also choose qualitative if my overall goal was to discover the truth.
6. Some challenges when it comes to combining methodologies when creating a research proposal, can be that quantitative and qualitative research do not align in their views. Another challenge is one researcher rarely is an expert in multiple methods. These challenges are not simple to overcome, however ways to overcome them are to work in a team of experts utilizing all fields of views. By using a multi-disciplinary approach to research, a team can be used to input their individual expertise. Such as pharmacist, physicians, microbiologist, etc.. Another way to combat these challenges would be to use a meta-analysis approach. This approach builds on research already conducted and can be answered in a more in-depth way compared to projects conducted individually. Most importantly to overcome these challenges, being flexible and adapting to the project is vital when combining methods.
7. When conducting a search, the majority of research tends to be quantitative in nature, particularly in healthcare (Tariq & Woodman, 2013). Combining methodologies means that both quantitative and qualitative methods are used within one research study. This can pose several challenges. First and foremost, implementing both methods can create a less coherent and more difficult-to-follow study. It is more time-consuming and creates more work for the researchers in order to determine how to combine, integrate, and interpret the data (Tariq & Woodman, 2013). Communicating the results from the combined research can also be challenging. After interpreting the data, researchers need to be able to present it in a coherent and easy to comprehend manner (Tariq & Woodman, 2013). There is a benefit to combining methodologies. One such benefit is that the combined method can address certain research questions in a more comprehensive manner (Tariq & Woodman, 2013). This allows for a more holistic understanding of the topic. Some ways to overcome these challenges are to plan accordingly by creating a detailed research plan. The objectives of the research should be clearly defined with a concrete timeline. Clear communication is probably one of the most important ways to overcome challenges. An explanation of the research design, methodology, and rationale for each methodology will create a coherent research study (Tariq & Woodman, 2013).

Introduction:
HIV/AIDS continues to be a significant global health challenge, and understanding its transmission, pathogenesis, clinical manifestations, treatment, and prevention is crucial in combating the disease. HIV primarily spreads through sexual contact, exposure to contaminated blood, and perinatal transmission. The virus targets CD4+ T cells, macrophages, and dendritic cells, leading to a decline in immune system function. As the disease progresses, individuals may experience flu-like symptoms, opportunistic infections, and malignancies. Antiretroviral therapy (ART) is the primary treatment for HIV/AIDS, which suppresses viral replication, preserves immune function, and reduces transmission. HIV prevention strategies include promoting safe sexual practices, ensuring the availability of clean needles, and early identification and treatment of HIV-infected individuals. A comprehensive understanding of HIV/AIDS is essential in addressing this global health issue (CDC, 2021; Koyama et al., 2020; Waymack & Sundareshan, 2021).
Answer to Question 2: Examples of Passive and Active Immunity
Passive immunity refers to the transfer of ready-made antibodies from one individual to another. It provides immediate but temporary protection against a specific antigen. Examples of passive immunity include the transfer of antibodies from a mother to her fetus or from a person who has already developed immunity to someone who is not immune. For instance, a baby receives passive immunity from their mother through the placenta or breast milk, protecting them from certain infections for the first few months of life.
On the other hand, active immunity refers to the immune response triggered by exposure to an antigen, leading to the production of specific antibodies and memory cells. Active immunity can be acquired either through natural infection or vaccination. An example of active immunity is when a person receives a vaccine containing weakened or inactive forms of a pathogen, stimulating the immune system to produce a response. This response creates memory cells that provide long-term protection against future infections.
Answer to Question 3: Transmission, Pathogenesis, Clinical Manifestations, Treatment, and Prevention of HIV/AIDS
Transmission: HIV/AIDS is primarily transmitted through sexual intercourse, exposure to contaminated blood or blood products, sharing needles or syringes among injection drug users, and maternal-child transmission (CDC, 2021). Genetic factors such as polymorphism of certain coreceptor molecules can influence the susceptibility of individuals to HIV infection. Additionally, a person’s viral load and the effectiveness of their immune function can impact the likelihood of transmission.
Pathogenesis: HIV initially infects macrophages and dendritic cells, which then travel to the lymph nodes and affect CD4+ T cells. The virus replicates, leading to flu-like symptoms. As more CD4+ T cells become infected, HIV replication increases. T cytotoxic (Tc) cells attempt to kill infected cells, and the bone marrow produces more CD4+ T cells to compensate. Eventually, the bone marrow becomes unable to produce enough CD4+ T cells, leading to the progression of HIV to AIDS.
Clinical Manifestations: Clinical manifestations of HIV/AIDS can differ depending on the stage of the disease. During the primary infection stage, individuals may experience fever, headache, muscle aches, rash, sore throat, swollen lymph glands, diarrhea, weight loss, cough, and night sweats. In the clinical latent infection stage, there may be no symptoms or infections, especially if antiretroviral therapy is being received. Symptomatic HIV infection includes the previously mentioned symptoms, as well as oral yeast infections, shingles, and pneumonia. Once the CD4+ T cell count falls below 200 cells/mm or opportunistic infections/cancers occur, HIV has progressed to AIDS. Other manifestations may include neurologic or metabolic complications and lesions on the tongue or mouth.
Treatment: Although there is currently no cure for HIV/AIDS, antiretroviral therapy (ART) can help slow disease progression. ART involves using a combination of different classes of drugs, such as nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase strand transfer inhibitors, and fusion inhibitors. Regular monitoring of CD4+ T cell levels, as well as lowering the viral load with ART and treating opportunistic infections, are also important components of HIV/AIDS treatment. Additionally, pre and post-exposure prophylaxis (PrEP and PEP) medications can be used to lower viral loads and prevent transmission.
Prevention: HIV prevention strategies include promoting safe sexual practices such as abstinence, consistent condom use, and reducing the number of sexual partners. Ensuring the availability of clean needles and syringes for injection drug users is crucial to prevent the transmission of HIV. Early identification and treatment of HIV-infected individuals can help control the spread of the disease. Pre-exposure prophylaxis (PrEP) is recommended for individuals at high risk of acquiring HIV, such as those in serodiscordant relationships or engaging in high-risk behaviors (CDC, 2021).
Answer to Question 4: Comparison of Quantitative and Qualitative Research
Quantitative research focuses on measuring and quantifying data, utilizing numerical analysis and statistical methods. It aims to describe and predict phenomena, based on objective observations and measurements. Its reliability and validity make it suitable for testing hypotheses, generalizing findings, and making predictions. In contrast, qualitative research involves gathering and interpreting non-numerical data such as interviews, documents, and observations. It aims to discover, understand, and interpret complex phenomena, relying on subjective experiences and interpretations.
While quantitative research relies on numerical data, qualitative research emphasizes context and meaning. The choice between quantitative and qualitative research depends on the research goals and the nature of the topic being studied. Quantitative research suits studies that require measuring variables, testing hypotheses, and generalizing findings. On the other hand, qualitative research is valuable for exploring complex phenomena, gaining in-depth insights, and understanding subjective experiences and perspectives. Researchers may prefer one approach over the other based on their comfort with numerical analysis and their goals for the research project.
Answer to Question 5: Differences between Quantitative and Qualitative Research
Quantitative research involves the collection and analysis of numerical data, aiming to describe, predict, and generalize findings. It focuses on measuring variables, testing hypotheses, and utilizing statistical methods. The goal is to create proposals that can be used to predict similar situations in the future. For example, quantitative research could be used to collect data on the incidence of patient falls in a hospital to identify factors contributing to falls and develop interventions to reduce them.
In contrast, qualitative research gathers and interprets non-numerical data to gain a deeper understanding of why or how certain phenomena occur. It explores meanings, experiences, and perspectives, relying on interviews, observations, and document analysis. Qualitative research seeks to discover new information and uncover complex issues that may not be captured by quantitative methods. For instance, qualitative research could be used to explore patients’ experiences of living with HIV/AIDS and the impact on their daily lives.
The choice between quantitative and qualitative research depends on the research goals and the type of information needed. Quantitative research provides reliable and valid data, suitable for testing hypotheses and making predictions. On the other hand, qualitative research offers rich and contextual information, valuable for exploring complex phenomena and gaining in-depth insights. Researchers should consider the nature of their research topic and the specific objectives of the study when deciding which approach to use.
Answer to Question 6: Challenges and Solutions in Combining Research Methodologies
Combining quantitative and qualitative research methodologies can present challenges due to differences in their underlying philosophies and approaches. One challenge is that quantitative research focuses on objectivity and generalizability, while qualitative research emphasizes subjectivity and context. Researchers may struggle to reconcile these differing perspectives when designing and conducting a study.
Another challenge is that researchers typically specialize in one methodology, and it is rare for individuals to be experts in both quantitative and qualitative methods. This can lead to difficulties in effectively implementing and integrating multiple methodologies within a single research project.
To overcome these challenges, interdisciplinary collaboration and teamwork are essential. Researchers from different disciplines and with expertise in various methodologies can work together to provide a comprehensive approach. Each researcher can contribute their respective knowledge and skills, ensuring that both quantitative and qualitative perspectives are adequately addressed.
Another approach is to use a meta-analysis or systematic review methodology. These methods involve synthesizing findings from multiple studies that have already been conducted. By combining and analyzing data from various quantitative and qualitative studies, researchers can provide a more comprehensive and in-depth understanding of the research topic.
Flexibility and adaptation are crucial when combining research methodologies. Researchers should be open to adjusting their methods and approaches based on the specific requirements of the study and the research question at hand. By embracing a flexible mindset, researchers can overcome challenges and create a robust research proposal that incorporates both quantitative and qualitative elements.
