Clinical determinants of radial artery caliber assessed at the time of transradial cardiac catheterization using routine prospective radiobrachial angiography.

BACKGROUND: Transradial coronary angiography/intervention (TRA/TRI) is associated with reduced rates of bleeding, vascular complications, and major adverse cardiovascular events as compared to the transfemoral approach, but remains underutilized in the United States (U.S.). Small radial caliber is often cited as a technical impediment, however radial artery diameter (RAD) has not yet been systematically studied in the U.S. population using routine, prospective radiobrachial angiography. METHODS: Consecutive patients (pts) with radiobrachial angiography acquired during TRA/TRI from September 2015 to August 2016 were retrospectively analyzed. Quantitative angiography (QA) was performed on digital subtraction angiograms. RAD measurements at distal (dRAD), mid (mRAD), and proximal (pRAD) segments, as well as minimum (minRAD) and maximum (maxRAD) diameters were indexed to radial arterial sheath size and tabulated. RAD measurements were adjudicated by 2 expert operators. Descriptive statistics and regression analyses were performed using STATA (College Station, TX). RESULTS: Of 175 radiobrachial angiograms, 2 were excluded due to uninterpretable QA. Woman had smaller RAD versus men: pRAD (3.11 vs 3.33 mm, p = 0.021), minRAD (2.36 vs 2.59 mm, p = 0.006), and maxRAD (3.32 vs 3.53 mm, p = 0.0195). Univariate analysis showed correlation between minRAD and gender (p = 0.012), age (p = 0.019), and weight (p = 0.008). However, after multivariate analysis, only gender was associated with minRAD (p = 0.05). CONCLUSION: This is the first study to describe the clinical determinants of RAD using prospective post-vasodilator, radiobrachial angiography in a U.S. POPULATION: Women had significantly smaller RAD across proximal, minimum, and maximum segments. Sex was the only multivariate predictor of minRAD.

Development of a macroprolactinoma in association with hormone replacement therapy in a perimenopausal woman with presumed idiopathic hyperprolactinemia.

OBJECTIVE: To describe a 48-year-old woman with presumed idiopathic hyperprolactinemia, who was found to have a macroprolactinoma after receiving hormone replacement therapy for almost 3 years. METHODS: We present a detailed case report, including a chronologic summary of clinical and laboratory findings as well as the drug history of our patient. The related literature is also reviewed. RESULTS: Premenopausal women with idiopathic hyperprolactinemia or microprolactinomas (<1 cm) are treated with dopamine agonists if fertility is desired or galactorrhea is bothersome. Otherwise, estrogens and progestational agents may be prescribed to regularize menses and prevent osteoporosis. Several case reports of prolactinoma formation or enlargement after exposure to exogenous estrogens have been published. In our patient, a perimenopausal woman with presumably idiopathic long-standing hyperprolactinemia, a macroprolactinoma developed within 3 years after initiation of hormone replacement therapy for management of perimenopausal symptoms. The only clue for ordering a pituitary imaging study in this case was a substantial increase in the level of the serum prolactin. Treatment with cabergoline normalized the patient's serum prolactin level and considerably decreased the size of her pituitary adenoma. CONCLUSION: It is postulated that exogenous estrogens could have an important role in tumor development or growth in some patients with idiopathic hyperprolactinemia. Therefore, it is recommended that women with idiopathic hyperprolactinemia or microprolactinomas treated with estrogens be considered for concomitant therapy with dopamine agonists. In all cases, serum prolactin levels should be diligently monitored.

The role of spirituality in the psychological adjustment to cancer: a test of the transactional model of stress and coping.

Recent studies in the oncology literature have shown that spirituality, defined as the combination of existential and religious well-being (RWB), is related to both emotional well-being and quality of life. Indeed, spirituality may be particularly important in coping with the potential life threat of the disease. Based on Frankl's (1963) existential theory, in this study, we examined whether the relations between spirituality and emotional well-being are moderated by degree of perceived life threat (PLT). In addition, in this study, we examined the relative importance of religious versus existential well-being in relation to psychological adjustment. Patients diagnosed with various types of cancer (N = 95) completed questionnaires assessing spirituality, PLT, quality of life, and distress. Contrary to theoretical predictions, spirituality was associated with less distress and better quality of life regardless of PLT. Interestingly, existential but not RWB accounted for a major portion of the variance in these outcomes. Taken together, these findings suggest that spirituality, particularly the existential component, may be associated with reduced symptoms of distress in cancer patients regardless of life threat.
