This article analyzes the clinical information obtained from a 38-year-old female marathon runner, Constantina, after her presentation at a general practice clinic after a training run.
The reproductive function of Constantina can be analyzed regarding endometrial tissue containing glandular structures that significantly contribute to glycogen secretion, which enhances blood flow in the spiral arteries in relation to elevated progesterone levels (Lessey & Young, 2019). Brame, Macedo, and Klein (2017) observe that high-intensity exercise in women leads to decreased progesterone levels, which subsequently results in diminished glycogen secretion from the glandular structures of endometrial tissue, potentially causing inadequate maintenance of the endometrium and menstrual irregularities. In the Constantina case study, Constantina's rigorous exercise regimen has diminished progesterone production, adversely impacting glandular tissue function and glycogen release, hence severely influencing reproductive function and the menstrual cycle.
The reproductive function is associated with the secretion of oestrogen, which plays a crucial role in sustaining reproductive capabilities, elevating cholesterol levels, and enhancing bone density (Vellanki, K., & Kramer, 2019). Estrogen levels typically increase during the follicular phase of the menstrual cycle, leading to the release of luteinizing hormone and follicle-stimulating hormone, while also supporting endometrial growth. However, Nagai et al. (2016) proposed that excessive exercise may disrupt normal estrogen secretion, resulting in diminished levels. Consequently, it can be said that Constantina engaging in rigorous exercise three times weekly may diminish the secretion of estrogen hormone from normal levels, leading to amenorrhea and impaired reproductive function.
In the Constantina case study, it is seen that Constantina exhibits lethargy and a reduction in fluid consumption, which may be associated with renal function. It is essential for maintaining fluid balance by controlling urine concentration and excretion via the reabsorption of bodily fluids in relation to the Antidiuretic hormone. The anti-diuretic hormone facilitates water retention in the body by enhancing water reabsorption in the late distal tubules and collecting ducts of the kidneys (Cuzzo & Lappin, 2019). It phosphorylates aquaporin-2, which enhances water transport across the osmotic gradient and sustains homeostasis. In the Constantina case study, Constantina is at risk of failing to maintain fluid balance due to her reported lower-than-usual water consumption, hence increasing the likelihood of dehydration. The physical examination detailed in the Constantina case study reveals lip dryness, periorbital dark circles, diminished skin turgor, and elevated urine specific gravity, all indicative of dehydration. Consequently, the depletion of bodily fluids in Constantina remains unaddressed, resulting in fluid imbalance.
A urinalysis was performed on Constantina to analyze the urine sample for diagnostic significance. Urinalysis involves the assessment of the appearance, composition, and concentration of urine to identify and treat various conditions, including renal diseases, urinary tract infections, and diabetes (Free, 2018). In the Constantina case study, the specific gravity (SG) of urine is recorded as 1.035, indicating a value in the elevated range. This indicates impaired kidney function related to renal tubule malfunction and antidiuretic hormone secretion. The inhibition of water reabsorption results in increased urine excretion and elevated solute concentration, thereby leading to significant water loss and dehydration (Perrier et al., 2017). Consequently, Constantina is at risk of failing to maintain fluid balance, resulting in elevated specific gravity in the urinalysis.
Gastrointestinal motility is essential for maintaining an individual's health. Gut motility pertains to the contractions and relaxations of the muscles inside the gastrointestinal (GI) tract, facilitating movements throughout the digestive system and the transit of contents, a process known as peristalsis (Beckett et al., 2017). Wood (2019) asserts that during dehydration, the gut absorbs a significant quantity of water from digested food, complicating excretion and obstructing peristaltic movement, which may be alleviated by increased water volume. As seen, the problem of dehydration in Constantina may result in a reduction of normal peristaltic movement.
The primary role of dietary protein is to sustain daily caloric intake, facilitate cellular and tissue repair, and stimulate muscle and body development. Constantina is a marathon runner, a discipline characterized by endurance, which may lead to tissue damage and suffering. Eddens et al. (2017) observed that protein consumption is crucial for tissue healing and cellular integrity, since it is metabolized into amino acids that facilitate cellular recovery. Consequently, she must sustain her protein consumption to fulfill her daily caloric requirements and support cellular repair by promoting muscle regeneration, so aiding in the regaining of strength (Cintineo et al., 2018).
The Constantina case study indicates that she is experiencing significant muscular discomfort and pain. To alleviate her sore muscles, Constantina used Voltaren Emulgel, which includes a nonsteroidal anti-inflammatory drug (NSAID). The NSAID component and active ingredient in this emulgel is diclofenac, which alleviates pain and diminishes inflammation. The delivery method is topical via the skin, with probable systemic absorption from the gastrointestinal tract and subsequent hepatic first-pass metabolism. Consequently, the relative bioavailability of diclofenac sodium was 6% of the systemic exposure, indicating a 94% reduction compared to oral diclofenac. This bioavailability is proportional to the treated area and is influenced by the total applied dose and the degree of skin hydration (Gopalasatheeskumar et al., 2017).
In this context, it is essential to highlight the significance of a drug's half-life. It denotes the duration required for the concentration of the medication in the plasma, or the total quantity of the drug inside the body, to diminish by 50% (Binder & Skerra, 2017). The drug's half-life is essential for administering and discontinuing drugs, alongside two other critical factors: potency and duration. This information seeks to determine whether drug buildup may arise from a regimen of several doses. Assuming 100% absorption and an NSAID half-life of 8 hours, 50% of the medication will be absorbed in the first 8 hours, and in the subsequent 8 hours, the remaining 50% will be reduced to 25% by the 16th hour. Moreover, after 24 hours, 12.5% of the first 25% will remain in the bloodstream.
Upon evaluating Constantina's blood pressure, it was recorded as 87/58 mm Hg. Normal blood pressure typically ranges from 110/70 mm Hg to 120/80 mm Hg. Consequently, the Constantina case study was anomalous. The typical range for mean arterial blood pressure (MABP) is 70-110 mm Hg, however in this instance, it displayed a lower figure. Zimmerman et al. (2017) indicated that an increase in blood viscosity results in heightened total peripheral resistance (TPR), consequently impeding blood flow. The correlation between mean arterial blood pressure (MABP), cardiac output, and total peripheral resistance (TPR) indicates that an elevation in systolic blood pressure is necessary to sustain blood volume. Consequently, reduced blood pressure in the Constantina case study results in diminished blood viscosity owing to a drop in total peripheral resistance. It induces an elevation in blood flow and a reduction in mean arterial blood pressure (MABP). Larsson et al. (2018) have suggested that a fall in mean arterial blood pressure (MABP) would result in a reduction in blood volume, obstructing flow in the glomerulus. Consequently, it modifies the renal reabsorption function.
A abrupt decrease in blood pressure in Constantina triggers the release of renin from the kidneys, activating the renin-angiotensin-aldosterone system (RAAS). It results in the synthesis of angiotensin I by the activation of angiotensinogen, which then transforms into angiotensin II. It secretes aldosterone hormones that directly operate in the kidneys (Ghazi & Drawz, 2017). It works by enhancing salt absorption and then releasing it into the bloodstream. The results from the Constantina case study indicate that to regulate blood pressure in her circumstance, the secretion of aldosterone elevates salt levels and blood volume, ultimately resulting in increased blood pressure.
In conclusion, the analysis of the Constantina case study indicates that her medical history, physical examination, and urinalysis provided critical insights into her dehydration and hypotension. The efficacy of these periodic pathological examinations may enhance therapy procedures to promote her health and wellness.
