RESUMO

ABSTRACT: The American Thyroid Association recommends levothyroxine monotherapy for treating hypothyroidism, a condition that affects 4.6% of the US population. However, up to 15% of these patients experience residual symptoms despite normalized thyroid-stimulating hormone levels, and may benefit from an endocrinology referral. Additional high-quality studies are needed to further evaluate patient preferences, as well as to investigate long-term outcomes of combination therapy and continue exploring therapeutic options for hypothyroidism management among specific patient subgroups.

RESUMO

BACKGROUND: There is limited data on the incidence of gastrointestinal-specific pathology in gender non-conforming (GNC) populations. METHODS: Retrospective analysis of pancreatitis incidence rates in transgender and GNC persons exposed and not exposed to gender-affirming hormone therapy (GAHT). RESULTS: 7 of the 1333 patients on hormone therapy had an incidence of pancreatitis. 0 of the 615 patients with no history of GAHT use developed pancreatitis. Representing a 6.96 (95% CI 2.76 to 848.78) for the development of pancreatitis in patients with exposure to GAHT therapy. CONCLUSION: Clinicians working with GNC individuals should be aware of this possible association.

RESUMO

Hypogonadism is a condition characterized by diminished or absent production of sex hormones by the testicles in men and the ovaries in women. Hypogonadism is classified into primary and secondary hypogonadism. Each type of hypogonadism can be caused by congenital and acquired factors. There are many factors that contribute to the occurrence of hypogonadism, including genetic and developmental disorders, infection, kidney disease, liver disease, autoimmune disorders, chemotherapy, radiation, surgery, and trauma. This represents the considerable challenge in diagnosing hypogonadism.The goals of treatment include restore sexual functionality and well-being, initiating and sustaining virilization, osteoporosis prevention, normalize growth hormone levels in elderly men if possible, and restoring fertility in instances of hypogonadotropic hypogonadism. The main approach to treating hypogonadism is hormone replacement therapy. Male with prostate cancer, breast cancer, and untreated prolactinoma are contraindicated for hormone replacement therapy. When selecting a type of testosterone therapy for male with hypogonadism, several factors need to be considered, such as the diversity of treatment response and the  type of testosterone formulation. The duration of therapy depends on individual response, therapeutic goals, signs and symptoms, and hormonal levels. The response to testosterone therapy is evaluated based on symptoms and signs as well as improvements in hormone profiles in the blood. Endocrine Society Clinical Practice Guideline recommend therapeutic goals based on the alleviation of symptoms and signs, as well as reaching testosterone levels between 400 - 700 ng/dL (one week after administering testosterone enanthate or cypionate) and maintaining baseline hematocrit.Hormone therapy is the primary modality in the management of hypogonadism. The variety of signs and symptoms makes early diagnosis of this condition challenging. Moreover, administering hypogonadism therapy involves numerous considerations influenced by various patient factors and the potential for adverse effects. This poses a challenge for physicians to provide targeted hypogonadism therapy with minimal complications.

RESUMO

OBJECTIVE: To assess menopausal symptoms and determine awareness of menopausal related information in mid-aged women. METHODS: This was a cross-sectional study in which 140 women aged 40 to 60 years from Guayaquil, Ecuador were surveyed with the short 10-item Cervantes Scale (CS-10) and a questionnaire containing personal data and questions assessing awareness of menopause related information. RESULTS: The mean age of the sample was 48.0 ± 5.6 years. More than half of surveyed women had low education and non-urban residency, none were on menopausal hormone therapy, 33.6% had hypertension, 35% were postmenopausal, 78.6% had an increased body mass index (overweight/obese) and 92.9% had abdominal obesity (waist > 88 cm). The average CS-10 score was 15.3 ± 9.0 with a median of 14.0. The three most frequent menopausal symptoms were muscle-joint pain (75.0%), changes in skin texture (74.3%) and vaginal dryness (71.4%). Regarding awareness of information related to the menopause, it was found that 98.6% of women had no idea about what the menopause is and the average age of its onset. Interestingly, although 61.4% knew that during the menopause there is weight gain, 57.9% were sedentary. Married, postmenopausal, older and less educated women presented higher mean total CS-10 scores. Contrarily, those with less awareness of menopause related information present lower scores. CONCLUSION: In this low-income mid-aged female sample there was a high rate of non-awareness regarding information related to the menopause, including an unhealthy cardiometabolic profile. There is a need for educational programs aimed to increase awareness in this high-risk population in relation to the surveyed aspects in order to improve their health status and prevent chronic conditions.

RESUMO

La terapia hormonal de afirmación de género con testosterona (GAHT, por sus siglas en inglés) permite, a las personas transgénero del espectro masculino, modificar las características sexuales secundarias del sexo asignado al nacer, aliviando así los síntomas de la disforia de género durante el proceso denominado transición. Sin embargo, se debe tener presente que se desconoce, en la actualidad, el efecto de la GAHT sobre la fertilidad a largo plazo, y el potencial efecto gonadotóxico de la misma. La demanda de un correcto asesoramiento reproductivo y la opción de realizar técnicas de preservación de la fertilidad (PF) han aumentado de forma exponencial en los últimos años, comportando cambios profundos en el manejo clínico de estas personas. En este artículo se realiza una revisión bibliográfica sobre el efecto de la GAHT a nivel reproductivo y en la fertilidad, junto con las técnicas de PF disponibles en este colectivo, principalmente la vitrificación de ovocitos. Además, realizamos un análisis de los resultados reproductivos publicados hasta la fecha tras el uso de técnicas de preservación, y exponemos los últimos avances de laboratorio en relación con la criopreservación de tejido ovárico y la maduración in vitro de ovocitos, junto con las opciones de futuro en población transgénero del espectro masculino.(AU)


Gender affirming hormone therapy (GAHT) in transmasculine people (individuals who identify as men or on the masculine spectrum and were assigned female sex at birth) makes it possible to modify the secondary sexual characteristics of the sex assigned at birth, thus alleviating the symptoms of gender dysphoria, during the process called transition. However, it is necessary to highlight that the effect of GAHT on long-term fertility and its potential gonadotoxic effects are currently unknown. Knowledge of the effects of testosterone on fertility and reproduction has increased recently, whilst the request for comprehensive reproductive counselling and the option of performing fertility preservation (FP) techniques have increased exponentially in recent years, leading to profound changes in the clinical management of this population. In this review, we analyzed all the information published regarding the effect of GAHT on reproduction and the FP techniques available in this group, mainly oocyte vitrification. In addition, we carry out an exhaustive analysis of the reproductive results published to date after the use of preservation techniques and present the latest laboratory advances concerning ovarian tissue cryopreservation and in vitro oocyte maturation, together with future options in the transmasculine people.(AU)

RESUMO

The purpose of this study is to compare the relative efficacy and safety of long-acting growth hormone (LAGH) as a growth hormone replacement therapy in prepubertal children with growth hormone deficiency (GHD). We searched the PubMed, Embase, CNKI, and Wanfang databases from inception to July 2023 and identified eleven relevant studies. PEG-LAGH showed better effect on height velocity (mean difference [MD]: - 0.031, 95% credibility interval [CrI]: - 0.278, 0.215) than somatrogon (MD: 0.105, 95% CrI: - 0.419, 0.636), somapacitan (MD: 0.802, 95% CrI: - 0.451, 2.068) and lonapegsomatropin (MD: 1.335, 95% CrI: - 0.3, 2.989) when compared with daily growth hormone (DGH). Furthermore, in terms of height standard deviation score, PEG-LAGH demonstrated better improvement (MD: - 0.15, 95% CrI: - 1.1, 0.66) than somatrogon (MD: - 0.055, 95% CrI: - 1.3, 0.51) and somapacitan (MD: 0.22, 95% CrI: - 0.91, 1.3). PEG-LAGH (risk ratio [RR]: 1.00, 95% CrI: 0.82, 1.2) reduced the risk of adverse events compared with other LAGH (somatrogon, RR: 1.1, 95% CrI: 0.98, 1.2; somapacitan, RR: 1.1, 95% CrI: 0.96, 1.4; lonapegsomatropin, RR, 1.1, 95% CrI: 0.91, 1.3) and was comparable with DGH. This is the first study to indirectly compare the LAGH thorough a network meta-analysis and provide evidence of the optimal efficacy of various LAGH specifically PEG-LAGH and acceptable safety profile in prepubertal children with GHD.

RESUMO

Introduction: Despite evidence from preclinical studies suggesting estrogen's neuroprotective effects, the use of menopausal hormone therapy (MHT) to support cognitive function remains controversial. Methods: We used random-effect meta-analysis and multi-level meta-regression to derive pooled standardized mean difference (SMD) and 95% confidence intervals (C.I.) from 34 randomized controlled trials, including 14,914 treated and 12,679 placebo participants. Results: Associations between MHT and cognitive function in some domains and tests of interest varied by formulation and treatment timing. While MHT had no overall effects on cognitive domain scores, treatment for surgical menopause, mostly estrogen-only therapy, improved global cognition (SMD=1.575, 95% CI 0.228, 2.921; P=0.043) compared to placebo. When initiated specifically in midlife or close to menopause onset, estrogen therapy was associated with improved verbal memory (SMD=0.394, 95% CI 0.014, 0.774; P=0.046), while late-life initiation had no effects. Overall, estrogen-progestogen therapy for spontaneous menopause was associated with a decline in Mini Mental State Exam (MMSE) scores as compared to placebo, with most studies administering treatment in a late-life population (SMD=-1.853, 95% CI -2.974, -0.733; P = 0.030). In analysis of timing of initiation, estrogen-progestogen therapy had no significant effects in midlife but was associated with improved verbal memory in late-life (P = 0.049). Duration of treatment >1 year was associated with worsening in visual memory as compared to shorter duration. Analysis of individual cognitive tests yielded more variable results of positive and negative effects associated with MHT. Discussion: These findings suggest time-dependent effects of MHT on certain aspects of cognition, with variations based on formulation and timing of initiation, underscoring the need for further research with larger samples and more homogeneous study designs.

RESUMO

Globally, 9 million women are diagnosed with cancer each year. Breast cancer is the most commonly diagnosed cancer worldwide, followed by colorectal cancer in high-income countries and cervical cancer in low-income countries. Survival from cancer is improving and more women are experiencing long-term effects of cancer treatment, such as premature ovarian insufficiency or early menopause. Managing menopausal symptoms after cancer can be challenging, and more severe than at natural menopause. Menopausal symptoms can extend beyond hot flushes and night sweats (vasomotor symptoms). Treatment-induced symptoms might include sexual dysfunction and impairment of sleep, mood, and quality of life. In the long term, premature ovarian insufficiency might increase the risk of chronic conditions such as osteoporosis and cardiovascular disease. Diagnosing menopause after cancer can be challenging as menopausal symptoms can overlap with other common symptoms in patients with cancer, such as fatigue and sexual dysfunction. Menopausal hormone therapy is an effective treatment for vasomotor symptoms and seems to be safe for many patients with cancer. When hormone therapy is contraindicated or avoided, emerging evidence supports the efficacy of non-pharmacological and non-hormonal treatments, although most evidence is based on women older than 50 years with breast cancer. Vaginal oestrogen seems safe for most patients with genitourinary symptoms, but there are few non-hormonal options. Many patients have inadequate centralised care for managing menopausal symptoms after cancer treatment, and more information is needed about cost-effective and patient-focused models of care for this growing population.

RESUMO

Lobular carcinoma represent the most common special histological subtype of breast cancer, with the majority classed as hormone receptor positive. Rates of invasive lobular carcinoma in postmenopausal women have been seen to increase globally, while other hormone receptor-positive breast cancers proportionally have not followed the same trend. This has been linked to exposure to exogenous ovarian hormones such as hormone replacement therapy. Reproductive factors resulting in increased lifetime exposure to endogenous ovarian hormones have also been linked to an increased risk of lobular breast cancer, and taken together, these data make a case for the role of ovarian hormones in the genesis and progression of the disease. In this review, we summarize current understanding of the epidemiological associations between ovarian hormones and lobular breast cancer and highlight mechanistic links that may underpin the etiology and biology.

RESUMO

For some transgender people, hormone replacement therapy (HRT) is "an ontological necessity for a livable life" (Fondén, 2020, p. 29). Some trans people engage in do-it-yourself (DIY) HRT (aka "DIYers") because of care barriers, including medication costs, difficulty accessing healthcare providers, and mistrust in professionalized medical systems. Although DIY HRT is often framed as highly risky, we analyzed in-depth interviews with 36 U.S. DIYers to understand how they themselves perceived their goals, challenges, and risk mitigation using the Liberatory Harm Reduction and lay expertise frameworks. Participants emphasized experiences of transphobia within medical spaces. In contrast, participants characterized DIY HRT as a community-driven, accessible, and empowering practice. Through self-organized online forums and mutual aid, DIYers constructed adaptive health-promoting practices that challenge biomedical conceptualizations of risk and affirm trans agency.

RESUMO

PURPOSE: To evaluate the role of serum progesterone (P4) on the day of embryo transfer (ET) when dydrogesterone (DYD) and micronized vaginal progesterone (MVP) are combined as luteal phase support (LPS) in a hormone replacement therapy (HRT) frozen ET (FET) cycles. METHODS: Retrospective study, including single euploid HRT FET cycles with DYD and MVP as LPS and P4 measurement on ET day. Initially, patients with P4 levels < 10 ng/ml increased MVP to 400 mg/day; this "rescue" was abandoned later. RESULTS: 560 cycles of 507 couples were included. In 275 women, serum P4 level was < 10 ng/ml on the ET day. Among those with low P4 levels, MVP dose remained unchanged in 65 women (11.6%) and was increased in 210 women (37.5%). Women with P4 levels ≥ 10 ng/ml continued LPS without modification. Overall pregnancy rates in these groups were 61.5% (40/65), 54.8% (115/210), and 48.4% (138/285), respectively (p = n.s.). Association of serum P4 levels with ongoing pregnancy rates was analyzed in women without any additional MVP regardless of serum P4 levels (n = 350); multivariable analysis (adjusted for age, BMI, embryo quality (EQ)) did not show a significant association of serum P4 levels with OPR (OR 0.96, 95% CI 0.90-1.02; p = 0.185). Using inverse probability treatment weights, regression analysis in the weighted sample showed no significant association between P4 treatment groups and OP. Compared to fair EQ, the transfer of good EQ increased (OR 1.61, 95% CI 1.22-2.15; p = 0.001) and the transfer of a poor EQ decreased the odds of OP (OR 0.73, 95% CI 0.55-0.97; p = 0.029). CONCLUSION: In HRT FET cycle, using LPS with 300 mg/day MVP and 30 mg/day DYD, it appears that serum P4 measurement and increase of MVP in patients with P4 < 10 ng/ml are not necessary.

RESUMO

Why compound bioidentical hormones? Are there no similar commercial products? What is unique about the options compounding pharmacists offer compared with what is out in the marketplace? These are questions that physicians and other practitioners are asking, and it is very important that we have intelligent, well-thought answers when we respond. Times have changed, and the challenges we face today in marketing our compounded therapies are not the same as those of twenty years ago. Premarin is no longer at the top of the heap, and there are topical, commercial products that contain bioidentical estradiol, and capsules that contain the same progesterone that we use. Our compounding advantage comes from our abilities to prepare unique patient-specific products, and, very importantly, from our growing understanding of hormone receptors; we now know there are two main estrogen receptors, 1) estrogen receptor alpha and 2) estrogen receptor beta, and the growing knowledge base associated with the discovery of estrogen receptor beta is quite significant.

RESUMO

Male hypogonadism is a condition that is receiving increasing medical scrutiny, resulting in research producing results favorable to the consideration of maintaining physiological levels of testosterone. As healthcare professionals interested in the health and welfare of a significant portion of the population, surely compounding pharmacists are interested in what can be done for men with this condition to help these patients improve their quality of life and long-term health. This article discusses the various ways that men's testosterone levels can be raised and provides insight into the importance of androgen-estrogen balance.

RESUMO

Less than optimal thyroid effects can occur for many reasons, including lack of production, excessive binding, reduced conversion to the active form of thyroid, poor intracellular transport, poor receptor response, or autoimmune and toxicity issues. Differentiation of where the problem or problems causing the symptoms of hypothyroidism to occur is a key to the return to optimal thyroid response and successful treatment outcome. The concept of hypothyroidism, functional hypothyroidism, and functional hypometabolism as an alternative method to describe classical subclinical hypothyroidism symptoms according to the source of the malfunction are discussed in this article. The author also presents a unique method of using standard thyroid measurements to determine the areas of dysfunction and discusses the possible reasons for low production, excessive binding, poor conversion, and suboptimal receptor response. Appropriate treatment options for each area are discussed, including nutritional requirements. Thyroid replacement therapy options are presented and individualization of therapy based on need established with use of the thyroid gradient levels is discussed. Individualization of thyroid therapy will often require the use of compounded T3 or T4/T3 combination therapy. Compounding thyroid replacement allows for avoiding fillers that can interfere with absorption, unwanted diluents, unknown or nonstandardized ingredients from animal sources, providing more sustained action with less side effects, and individualizing the ratio of T4 and T3 initially, and as improvements are made in the patient's ability to convert T4 to T3.

RESUMO

STUDY QUESTION: Is there a significant intra-individual variability of serum progesterone levels on the day of single blastocyst Hormone Replacement Therapy-Frozen Embryo Transfer (HRT-FET) between two consecutive cycles? SUMMARY ANSWER: No significant intra-individual variability of serum progesterone (P) levels was noted between two consecutive HRT-FET cycles. WHAT IS KNOWN ALREADY: In HRT-FET cycles, a minimum P level on the day of embryo transfer is necessary to optimise reproductive outcomes. In a previous study by our team, a threshold of 9.8 ng/ml serum P was identified as significantly associated with the live birth rates in single autologous blastocyst transfers under HRT using micronized vaginal progesterone (MVP). Such patients may benefit from an intensive luteal phase support (LPS) using other routes of P administration in addition to MVP. A crucial question in the way towards individualising LPS is whether serum P measurements are reproducible for a given patient in consecutive HRT-FET cycles, using the same LPS. STUDY DESIGN, SIZE, DURATION: We conducted an observational cohort study at the university-based reproductive medicine centre of our institution focusing on women who underwent at least two consecutive single autologous blastocyst HRT-FET cycles between January 2019 and March 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients undergoing two consecutive single autologous blastocyst HRT-FET cycles using exogenous oestradiol and vaginal micronized progesterone for endometrial preparation were included. Serum progesterone levels were measured on the morning of the Frozen Embryo Transfer (FET), by a single laboratory. The two measurements of progesterone levels performed on the day of the first (FET1) and the second FET (FET2) were compared to evaluate the intra-individual variability of serum P levels. Paired statistical analyses were performed, as appropriate. MAIN RESULTS AND THE ROLE OF CHANCE: Two hundred and sixty-four patients undergoing two consecutive single autologous blastocyst HRT-FET were included. The mean age of the included women was 35.0 ± 4.2 years. No significant intra-individual variability was observed between FET1 and FET2 (mean progesterone level after FET1: 13.4 ± 5.1 ng/ml vs after FET2: 13.9 ± 5.0; P = 0.08). The characteristics of the embryo transfers were similar between the first and the second FET. Forty-nine patients (18.6%) had discordant progesterone levels (defined as one progesterone measurement > and one ≤ to the threshold of 9.8 ng/ml) between FET1 and FET2. There were 37/264 women (14.0%) who had high intra-individual variability (defined as a difference in serum progesterone values >75th percentile (6.0 ng/ml)) between FET1 and FET2. No specific clinical parameter was associated with a high intra-individual variability nor a discordant P measurement. LIMITATIONS, REASONS FOR CAUTION: This study is limited by its retrospective design. Moreover, only women undergoing autologous blastocyst HRT-FET with MVP were included, thereby limiting the extrapolation of the study findings to other routes of P administration and other kinds of endometrial preparation for FET. WIDER IMPLICATIONS OF THE FINDINGS: No significant intra-individual variability was noted. The serum progesterone level appeared to be reproducible in >80% of cases. These findings suggest that the serum progesterone level measured on the day of the first transfer can be used to individualize luteal phase support in subsequent cycles. STUDY FUNDING/COMPETING INTEREST(S): No funding or competing interests. TRIAL REGISTRATION NUMBER: N/A.
