    Insights

    Lyme disease (LD) diagnosis relies on current antibody tests, but these often miss early infections. Newer, more sensitive lab techniques are being developed for earlier and more accurate detection of Borrelia burgdorferi.

    Area of Science:

    • Medical Entomology
    • Infectious Diseases
    • Clinical Diagnostics

    Background:

    • Lyme disease (LD) is the most common tick-borne illness in the Northern Hemisphere, affecting 300,000 people annually in the USA.
    • Caused by Borrelia burgdorferi, LD can spread to multiple organs if not treated early, leading to severe health complications.

    Purpose of the Study:

    • To review current clinical diagnostic assays for Lyme disease.
    • To establish a foundation for exploring novel, more sensitive laboratory techniques for early LD detection.

    Main Methods:

    • Review of current serological testing methods for LD diagnosis.
    • Discussion of the limitations of existing diagnostic algorithms, such as the two-tier assay (ELISA and western blot).

    Main Results:

    • Current diagnostic methods, including the two-tier algorithm, are hampered by low sensitivity, potentially leading to missed early Lyme disease cases.
    • Early detection and antibiotic treatment are crucial for optimal outcomes in Lyme disease management.

    Conclusions:

    • There is a need for more sensitive diagnostic assays to improve early detection of Lyme disease.
    • Ongoing research into newer laboratory techniques holds promise for more accurate and timely diagnosis of LD.

    Nursing Diagnosis01:22

    Nursing Diagnosis

    Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
    The nursing diagnosis focuses on evidence-based...

    Formulating and Validating Nursing Diagnosis I

    A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
    There are thirteen domains...

    Documentation of Nursing Diagnosis01:10

    Documentation of Nursing Diagnosis

    The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
    In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

    Persuasion Strategies

    Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

    Formulating and Validating Nursing Diagnosis II

    Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.
    Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...

    Diabetes: Symptoms, Diagnosis, and Complications

    For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
