Filter by:Low levels of serum triiodothyronine (T3) thyroid hormones (T4) are a strong predictor of mortality and poor prognosis in critical care patients. Few reports, however, have focused on neurocritical patients. Patients with severe neurological diseases often experience more complications and exhibit higher mortality rates, and many studies have provided evidence for a low T3/T4 state being an important prognostic indicator in such cases; Lieberman et al. found that 87% of individuals with severe traumatic brain injury have thyroid function below the mid-normal range. Other researchers showed that low T3 syndrome is a predictor of poor prognosis in cerebral infarction patients; their findings indicated the central hypothyroidism and disturbance of thyroid hormone metabolism were involved. Low T3 syndrome is common in patients with brain tumors and has been shown to be associated with shorter survival in glioma patients. Despite these observations, however, whether the thyroid hormone abnormalities in the critically ill are a physiological adaptation or a pathological change, and whether hormone replacement therapy (HRT) can benefit such patients, remain to be established. As acute progression ceases, thyroid hormone levels may return to normal. This may imply that thyroid hormone supplements could improve the prognosis of patients with secondary hypothyroidism. Previous clinical studies have examined the effect of thyroid HRT on patients undergoing cardiac surgery; patients with malnutrition, heart failure, or acute renal failure; and premature infants with acute respiratory distress syndrome. Most of these past studies found no significant positive effects on prognosis, and no harmful effects either. Some smaller studies have demonstrated potential promise for the use of HRT; for example, one study showed that T3 supplementation in patients undergoing cardiac surgery could lead to less need for inotropic support and better hemodynamic parameters. There are no reports of thyroid HRT improving the prognosis of neurocritical patients with secondary hypothyroidism. The application of hormone replacement therapy in the treatment of neurocritical patients with secondary hypothyroidism remains controversial. This study aims to explore the safety and effectiveness of thyroid hormone replacement therapy in patients with spontaneous intracerebral hemorrhage and concomitant secondary hypothyroidism.
The aim of the study is to follow acoustic and perceptual voice changes in trans men during hormone therapy and to examine the relationship between psychosocial and vocal characteristics and testosterone measured in routine follow-up in accordance with international follow-up guidelines.
This study will find out what the reference intervals are for common blood tests in transgender people taking hormone therapy. Reference intervals help doctors interpret blood test results. They are expressed as two numbers, and most normal results fall between them. If a results fall outside of them, it may be because of a disease. Some blood tests are also affected by normal difference between people, such as age, sex or ethnicity. For these tests, different reference intervals are given for each group of people. Having accurate reference intervals benefits patients because it allows doctors to identify disease faster. Transgender people have a gender identity which does not match their sex characteristics at birth. Gender identity is the feeling of being a gender, and sex is the biological aspects of growing up male or female. Transgender people may use hormone therapy to help change their appearance to fit their gender identity. This involves taking either oestrogen or testosterone. For blood tests which are affected by sex, it is not clear what reference intervals should be used for transgender people who are on hormone therapy. This is because they have a mixture of male and female sex characteristics. Answering this question will allow doctors to identify disease in them faster. The study will take place at cliniQ, at King's College Hospital, which provides health services to transgender people. It will recruit healthy transgender people who attend the clinic for blood tests to monitor their hormone therapy. Participants will fill out a questionnaire, give a urine sample, then have their appointment as normal. Extra tests will also be performed on their blood sample. The aim is to recruit 240 participants. Participant's tests results will then be used to calculate reference intervals. The study is funded by Viapath Group LLP.
Menopause is defined as the last episode of menstrual bleeding, resulting from the interruption of ovarian function by follicular depletion. It is characterized by the presence of amenorrhea associated with increased levels of FSH and low levels of estradiol. The decline in estrogenic levels is associated with several organic changes, from vasomotor symptoms to impaired bone mass and urogenital atrophy. Although for some patients menopause is asymptomatic or oligosymptomatic, many women experience intense symptoms, which profoundly affect quality of life. Proper assessment and treatment of postmenopausal women can significantly improve climacteric symptoms. Target tissue, hormone therapy regimen and variations between patients will influence the effects of treatment. Regarding estrogen, the main factors that influence the therapeutic response are the type of hormone used, the dose and the route of administration. The skin metabolizes only a small part of estradiol. Thus, the transdermal route reaches adequate therapeutic levels from a lower dose of estrogen. The present study aims to evaluate and compare the effects of low dose of oral estradiol associated with oral progesterone and transdermal estradiol associated with vaginal progesterone on variables related to inflammation, coagulation and body composition parameters.
The purpose of this study is to evaluate the effects on breast in postmenopausal women randomized to either oestradiol in combination with DRSP or E2 in combination with NETA during six months.
