RESUMO

Increasing numbers of transgender and gender-diverse (TGD) youth, from early puberty through late adolescence, are seeking medical services to bring their physical sex characteristics into alignment with their gender identity-their inner sense of self as male or female or elsewhere on the gender spectrum. Numerous studies, primarily of short- and medium-term duration (up to 6 years), demonstrate the clearly beneficial-even lifesaving-mental health impact of gender-affirming medical care in TGD youth. However, there are significant gaps in knowledge and challenges to such care. Long-term safety and efficacy studies are needed to optimize medical care for TGD youth.

RESUMO

Transgender people often face barriers in health care due to lack of access to care, lack of knowledgeable healthcare professionals, discrimination, and gaps in medical and mental health research. Existing research on transgender health has focused heavily on mental health, HIV/AIDS, sexually transmitted diseases/infections, and substance abuse. Gender-affirming hormone therapy and/or surgery allows for some alignment of biology and gender identity. Gender-affirming care may offer quality-of-life benefits, which may outweigh modest concerns related to exogenous hormone therapy. The Endocrine Society treatment guidelines were revised in 2017, and this article reviews recent data that might inform a future guideline revision. Future longitudinal research is needed to close the gap in knowledge in the field of transgender medicine.

RESUMO

Transgender identity is often associated with gender dysphoria and minority stress. Gender-affirming hormone treatment (GAHT) includes masculinising or feminising treatment and is expected to be lifelong in most cases. Sex and sex hormones have a differential effect on metabolism and CVD in cisgender people, and sex hormone replacement in hypogonadism is associated with higher vascular risk, especially in ageing individuals. Using narrative review methods, we present evidence regarding metabolic and cardiovascular outcomes during GAHT and propose recommendations for follow-up and monitoring of metabolic and cardiovascular risk markers during GAHT. Available data show no increased risk for type 2 diabetes in transgender cohorts, but masculinising GAHT increases lean body mass and feminising GAHT is associated with higher fat mass and insulin resistance. The risk of CVD is increased in transgender cohorts, especially during feminising GAHT. Masculinising GAHT is associated with a more adverse lipid profile, higher haematocrit and increased BP, while feminising GAHT is associated with pro-coagulant changes and lower HDL-cholesterol. Assigned male sex at birth, higher age at initiation of GAHT and use of cyproterone acetate are separate risk factors for adverse CVD markers. Metabolic and CVD outcomes may improve during gender-affirming care due to a reduction in minority stress, improved lifestyle and closer surveillance leading to optimised preventive medication (e.g. statins). GAHT should be individualised according to individual risk factors (i.e. drug, dose and form of administration); furthermore, doctors need to discuss lifestyle and preventive medications in order to modify metabolic and CVD risk during GAHT. Follow-up programmes must address the usual cardiovascular risk markers but should consider that biological age and sex may influence individual risk profiling including mental health, lifestyle and novel cardiovascular risk markers during GAHT.

RESUMO

KNOXs, a type of homeobox genes that encode atypical homeobox proteins, play an essential role in the regulation of growth and development, hormonal response, and abiotic stress in plants. However, the KNOX gene family has not been explored in sweet potato. In this study, through sequence alignment, genomic structure analysis, and phylogenetic characterization, 17, 12 and 11 KNOXs in sweet potato (I. batatas, 2n = 6x = 90) and its two diploid relatives I. trifida (2n = 2x = 30) and I. triloba (2n = 2x = 30) were identified. The protein physicochemical properties, chromosome localization, phylogenetic relationships, gene structure, protein interaction network, cis-elements of promoters, tissue-specific expression and expression patterns under hormone treatment and abiotic stresses of these 40 KNOX genes were systematically studied. IbKNOX4, -5, and - 6 were highly expressed in the leaves of the high-yield varieties Longshu9 and Xushu18. IbKNOX3 and IbKNOX8 in Class I were upregulated in initial storage roots compared to fibrous roots. IbKNOXs in Class M were specifically expressed in the stem tip and hardly expressed in other tissues. Moreover, IbKNOX2 and - 6, and their homologous genes were induced by PEG/mannitol and NaCl treatments. The results showed that KNOXs were involved in regulating growth and development, hormone crosstalk and abiotic stress responses between sweet potato and its two diploid relatives. This study provides a comparison of these KNOX genes in sweet potato and its two diploid relatives and a theoretical basis for functional studies.

RESUMO

BACKGROUND: The WRKY gene family is one of the largest families of transcription factors in higher plants, and WRKY transcription factors play important roles in plant growth and development as well as in response to abiotic stresses; however, the WRKY gene family in pea has not been systematically reported. RESULTS: In this study, 89 pea WRKY genes were identified and named according to the random distribution of PsWRKY genes on seven chromosomes. The gene family was found to have nine pairs of tandem duplicates and 19 pairs of segment duplicates. Phylogenetic analyses of the PsWRKY and 60 Arabidopsis WRKY proteins were performed to determine their homology, and the PsWRKYs were classified into seven subfamilies. Analysis of the physicochemical properties, motif composition, and gene structure of pea WRKYs revealed significant differences in the physicochemical properties within the PsWRKY family; however, their gene structure and protein-conserved motifs were highly conserved among the subfamilies. To further investigate the evolutionary relationships of the PsWRKY family, we constructed comparative syntenic maps of pea with representative monocotyledonous and dicotyledonous plants and found that it was most recently homologous to the dicotyledonous WRKY gene families. Cis-acting element analysis of PsWRKY genes revealed that this gene family can respond to hormones, such as abscisic acid (ABA), indole-3-acetic acid (IAA), gibberellin (GA), methyl jasmonate (MeJA), and salicylic acid (SA). Further analysis of the expression of 14 PsWRKY genes from different subfamilies in different tissues and fruit developmental stages, as well as under five different hormone treatments, revealed differences in their expression patterns in the different tissues and fruit developmental stages, as well as under hormone treatments, suggesting that PsWRKY genes may have different physiological functions and respond to hormones. CONCLUSIONS: In this study, we systematically identified WRKY genes in pea for the first time and further investigated their physicochemical properties, evolution, and expression patterns, providing a theoretical basis for future studies on the functional characterization of pea WRKY genes during plant growth and development.

RESUMO

STUDY QUESTION: What are the sonographic and clinical findings in women diagnosed with external and internal adenomyosis by ultrasound? SUMMARY ANSWER: Patients with external and internal adenomyosis phenotypes, diagnosed by ultrasound, present differences in sonographic features of the disease and demographic characteristics including age, parity, and association with deep endometriosis (DE) and leiomyomas. WHAT IS KNOWN ALREADY: Two different phenotypes of adenomyosis have been described based on the anatomical location of adenomyotic lesions in the myometrium, suggesting that adenomyosis affecting the inner myometrium and that affecting the external myometrial layer may have distinct origins. STUDY DESIGN, SIZE, DURATION: A cross-sectional study including 505 patients with a sonographic diagnosis of adenomyosis was performed between January 2021 and December 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women sonographically diagnosed with adenomyosis in a tertiary referral hospital that serves as a national reference center for endometriosis were included over a 2-year period. Patients were divided into two groups (internal and external adenomyosis) according to the myometrial layer affected by adenomyosis. We compared sonographic and clinical outcomes including a multivariate analysis between the two groups. MAIN RESULTS AND THE ROLE OF CHANCE: According to ultrasound findings, 353 (69.9%) patients presented with internal adenomyosis, while 152 (30.1%) presented with external adenomyosis. Women with internal adenomyosis were significantly older and less frequently nulliparous compared to those with external adenomyosis. Sonographically, internal adenomyosis appeared diffusely, it had a greater number of adenomyosis features, it presented a globular morphology of the uterus more frequently, and it coexisted with leiomyomas more frequently, compared to external adenomyosis. Conversely, the presence of translesional vascularity and associated DE were more common among the external adenomyosis group. No significant differences were found between internal and external adenomyosis groups regarding pain, heavy menstrual bleeding, spotting, or infertility. In the multivariate analysis, nulliparity, the presence of leiomyomas, and the presence of DE were independently associated with adenomyosis phenotypes (the presence of DE and nulliparity increased the risk of external adenomyosis, whereas the presence of leiomyomas was a risk factor for internal adenomyosis). Considering the impact of hormonal treatment, we found that the number of ultrasound adenomyosis criteria was significantly greater in patients without hormonal treatment. Non-treated patients more commonly presented dysmenorrhea or bleeding-associated pain and heavy menstrual bleeding than women on hormonal treatment, although there were no significant differences according to adenomyosis phenotypes. LIMITATIONS, REASONS FOR CAUTION: As the population was selected from the Endometriosis Unit of a tertiary center, there may be patient selection bias, given the high prevalence of individuals with associated endometriosis, previous endometriosis-related surgery, and/or receiving hormonal treatment. WIDER IMPLICATIONS OF THE FINDINGS: Transvaginal ultrasound is the most available and cost-effective tool for the diagnosis of adenomyosis. Adenomyosis phenotypes based on ultrasound findings may be key in achieving an accurate diagnosis and in decision-making regarding the most adequate therapeutic strategy for the management of patients with adenomyosis. Determination of the sonographic features associated with symptoms could help in the evaluation of treatment response. STUDY FUNDING/COMPETING INTEREST(S): No funding was obtained for this study and there are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: N/A.

RESUMO

Testosterone may reduce pain in cisgender women and transgender men. Rodents can provide a useful model for investigating physiological effects of hormone therapy. To this end, continuous-release testosterone or blank (placebo) capsules were implanted s.c. into young adult female rats, and three weeks later rats were either ovariectomized or sham-ovariectomized. Testosterone treatment that mimicked previously reported endogenous levels in males eliminated estrous cycling and decreased uterine weight. Testosterone also significantly increased body weight and suppressed the increases in daily wheel running observed in placebo controls over time. Subsequent ovariectomy or sham-ovariectomy decreased wheel running in all groups, but testosterone-treated rats recovered significantly more quickly than did placebo-treated rats. Neither testosterone nor ovariectomy significantly altered hindpaw mechanical threshold. Two weeks after sham/ovariectomy surgery, injection of Complete Freund Adjuvant (CFA) into one hindpaw reduced wheel running and mechanical threshold in all groups; running significantly decreased from the first to second day after CFA in testosterone- but not in placebo-treated rats. Morphine 1.0 but not 3.2 mg/kg increased CFA-suppressed wheel running similarly in all groups, whereas both doses of morphine increased CFA-suppressed mechanical threshold. These data suggest that weeks-long testosterone treatment with or without ovariectomy may provide a useful physiological model of testosterone therapy as used in human gender transition. Although testosterone administered at levels similar to those in gonadally intact males tended to hasten female rats' recovery from surgery, it did not decrease maximal pain-related behaviors after surgery or hindpaw inflammatory insult, nor did it alter opioid antinociception.

RESUMO

OBJECTIVE: To assess the association between achievement of prostate-specific antigen (PSA) levels ≤0.2 ng/mL (henceforth 'ultralow') and clinical outcomes in patients in the 'Targeted Investigational Treatment Analysis of Novel Anti-androgen' (TITAN) study (ClinicalTrials.gov Identifier NCT02489318) with metastatic castration-sensitive prostate cancer (mCSPC). PATIENTS AND METHODS: Patients in the TITAN study with mCSPC were randomised to 240 mg/day apalutamide (n = 525) or placebo (n = 527) plus androgen-deprivation therapy. This post hoc analysis assessed the achievement of a PSA level of 0.2->0.02 ng/mL ('ultralow one' [UL1]) and ≤0.02 ng/mL ('ultralow two' [UL2]) vs >0.2 ng/mL with apalutamide treatment and its association with radiographic progression-free survival (rPFS), overall survival (OS), time to castration-resistant PC (TTCRPC), and time to PSA progression (TTPP). The landmark analysis and Kaplan-Meier methods were used. RESULTS: By 3 months, more patients achieved UL1 and UL2 with apalutamide (38% and 23%) vs placebo (15% and 5%). In the apalutamide-treated patients, UL2 vs PSA >0.2 ng/mL at landmark 3 months was associated with significantly longer rPFS (hazard ratio [HR] 0.28, 95% confidence interval [CI] 0.14-0.54), OS (HR 0.24, 95% CI 0.13-0.43), TTCRPC (HR 0.2, 95% CI 0.11-0.38), and TTPP (HR 0.11, 95% CI 0.04-0.27; nominal P values all <0.001); this association was also observed but less pronounced for UL1. Similar findings were observed at 6 months. Early onset of decline to UL2 by 3 months was associated with improved survival vs PSA >0.2 ng/mL anytime (HR 0.12, 95% CI 0.06-0.22; P < 0.001) in apalutamide-treated patients. CONCLUSIONS: In this post hoc analysis of TITAN, patients with the deepest PSA decline derived the greatest benefit. These results extend our findings of apalutamide efficacy in the overall TITAN population, underscoring the clinical value of PSA kinetics as a marker for treatment efficacy. PATIENT SUMMARY: Patients with metastatic prostate cancer that is sensitive to ongoing hormonal treatment benefited significantly from the addition of apalutamide compared with placebo. Those who achieved rapid and deep PSA reduction had the greatest survival benefit.

RESUMO

PURPOSE: The primary objective was to establish whether blood-based leucine-rich alpha-2-glycoprotein (LRG1) can predict outcomes in patients with locally advanced prostate cancer undergoing androgen-deprivation therapy (ADT) and radiotherapy (RT) and to determine how it may relate to 92 immune-oncology (I-O)-related proteins in this setting. METHODS: Baseline blood level of LRG1 from patients treated with ADT and RT enrolled in the CuPCa (n = 128) and IMRT (n = 81) studies was measured using ELISA. A longitudinal cohort with matched blood samples from start of ADT, start of RT, and end of RT protocol from 47 patients from the IMRT cohort was used to establish levels of I-O proteins by high-multiplexing Proximal Extension Assay by Olink Proteomics. Statistical analyses using Kaplan-Meier, Cox regression, and LIMMA analyses were applied to predict the prognostic value of LRG1 and its correlation to I-O proteins. RESULTS: High baseline levels of LRG1 predicted a low frequency of treatment failure in patients undergoing ADT + RT in both the CuPCa and the IMRT cohorts. LRG1 was moderately correlated with CD4, IL6, and CSF1. We identified I-O proteins predicting metastatic failure (MF) at different timepoints. CONCLUSION: LRG1 biomarker is associated with I-O proteins and can be used to improve stratification and monitoring of prostate cancer patients undergoing ADT + RT. This work will require further in-depth analyses in independent cohorts with treatment outcome data.

RESUMO

A network of healthcare professionals specializing in transgender care was established in Croatia in 2011, and legal advancements were subsequently made in 2014. Both achievements made gender transition more transparent and thus more attainable in Croatia. This observational study was conducted to assess the number of transgender individuals initiating gender-affirming hormone treatment (GAHT) in Croatia and describes trends in age and sex assigned at birth. Between 2011 and 2022, a total of 111 transgender individuals initiated GAHT. Within the cohort, 52 were assigned male at birth (AMAB) and 59 were assigned female at birth (AFAB). The overall annual incidence rate of transgender individuals initiating GAHT was 0.52 per 100,000 age-adjusted individuals. There was a statistically significant increase (p < 0.01) in transgender individuals commencing GAHT before the COVID-19 pandemic. Furthermore, a rising trend toward masculinizing rather than feminizing treatment was identified (p < 0.05), particularly among younger transgender individuals. The COVID-19 pandemic disrupted these trends in 2020, except for the trend of initiating therapy at a younger age (p < 0.01). The annual incidence and age distribution trends of transgender individuals initiating GAHT in Croatia closely mirrored those in other European countries, with a higher prevalence of individuals assigned female at birth. The study underscores a significant rise in the number of individuals initiating gender-affirming hormone treatment, emphasizing the need for proper legal regulation and healthcare system response.

RESUMO

Although the coronavirus disease 2019 (COVID-19) pandemic accelerated the adoption and expansion of telemedicine worldwide, little is known about the transition to home-based care for children. This study aims to investigate the facilitators and barriers to the transition from outpatient clinic visits to home-based check-ups (HBCU), for children being treated with growth hormone. A mixed-methods study was performed at Amalia Children's Hospital (Radboud University Medical Centre, Nijmegen), consisting of questionnaires and semi-structured and focus group interviews. For the quantitative part, the Measurement Instrument for Determinants of Innovation (MIDI) was utilised to investigate the facilitators and barriers for the 81 participants regarding the transition to HBCU. The MIDI questionnaire is comprised of four domains: the innovation-, user-, organisation-, and the socio-political scale. Descriptive statistics were performed for analysing the questionnaires. For the qualitative part, interviews with 10 participants derived from the questionnaire and the two focus group interviews were conducted, to gain more in-depth information about the research topic, until data saturation was reached. The interviews were analysed by using the reflective thematic approach, starting with deductive coding and followed by inductive coding. Several facilitators were recognised in our study: procedural clarity, self-efficacy, convenience, patient-centred care, increased accuracy in height measurements, social support, client/patient satisfaction/cooperation, patient-centred care, the flexibility and adaptivity of HBCU, physical start-up period of HBCU, and a potential decrease in healthcare costs. However, several barriers were also noted in our study: poor compatibility with current practice, lack of consultation within the team, feeling of being less controlled by physicians, unsettledness of the organisation, an increased workload for the staff, and insufficient information communication technology (ICT) facilities. CONCLUSION: This study revealed that HBCU have considerable benefits for both patients and healthcare professionals, from the standpoint of innovation, user, and socio-political points of view. The identified facilitators and barriers to HBCU should be taken into account when further steps of implementing HBCU are considered. WHAT IS KNOWN: • The Corona-Virus-Disease 2019 (COVID-19) pandemic has had an immense impact on health care worldwide. A substantial amount of the outpatient clinic visits for children treated with growth hormone was, as a result of the pandemic, transferred to online consultation. Transitioning paediatric growth hormone treatment to the home setting may be favorable for children and their parents/caregivers) as well for healthcare professionals. • Insights regarding facilitators and barriers is vital for the successful implementation and adoption of home-care technologies. WHAT IS NEW: • To our knowledge, we are first to report on and explicit the facilitators and barriers of the transition to home-based check-ups, via online consultation for children being treated with growth hormone. • Both children and healthcare professionals reported major facilitators and some minor barriers to the transition to home-based check-ups, illustrating their potential value. These facilitators and barriers should be considered while working towards implementation of home-based check-ups.

RESUMO

Patients with Aarskog-Scott syndrome (AAS) have short stature, facial anomalies, skeletal deformities, and genitourinary malformations. FYVE, RhoGEF, and PH domain-containing 1 (FGD1) is the only known causative gene of AAS. However, the diagnosis of AAS remains difficult, and specific treatments are still absent. Patients suspected with AAS were recruited, and clinical information was collected. Genetic testing and functional analysis were carried out for the diagnosis. By literature review, we summarized the clinical and genetic characteristics of FGD1-related AAS and analyzed the genotype-phenotype correlation. Five patients were recruited, and four novel FGD1 variants were identified. The diagnosis of AAS was confirmed by genetic analysis and functional study. Three patients treated with growth hormone showed improved heights during the follow-up period. By literature review, clinical features of AAS patients with FGD1 variants were summarized. Regarding FGD1 variations, substitutions were the most common form, and among them, missense variants were the most frequent. Moreover, we found patients with drastic variants showed higher incidences of foot and genitourinary malformations. Missense variants in DH domain were related to a lower incidence of cryptorchidism.   Conclusion: We reported four novel pathogenic FGD1 variations in AAS patients and confirmed the efficacy and safety of growth hormone treatment in FGD1-related AAS patients with growth hormone deficiency. Additionally, our literature review suggested the crucial role of DH domain in FGD1 function. What is Known: • Aarskog-Scott syndrome is a rare genetic disease, and the only known cause is the variant in FGD1 gene. The typical clinical manifestations of AAS include facial, skeletal, and urogenital deformities and short stature. What is New: • We reported four novel FGD1 variants and reported the treatment of growth hormone in FGD1-related AAS patients. Our genotype-phenotype correlation analysis suggested the crucial role of DH domain in FGD1 function.

RESUMO

OBJECTIVE: The aim of this study was to explore the impact of growth hormone (GH) therapy on the onset and progression of puberty in girls with idiopathic short stature. METHODS: This study included 541 girls aged between 4.5 and 10.6 years who were receiving GH treatment, monitored over a 22-year follow-up period. Of these, 126 girls have been followed up to the onset of menarche. The participants were divided into two groups: a ISS control group (n = 66) and a group receiving daily GH treatment at a dose of 0.15 iu/kg (n = 60). We assessed the pubertal development and GH usage of these girls every three months. RESULTS: (1) There was no significant difference in the onset of puberty between the growth hormone (GH) treatment group and the control group; however, the average duration of puberty was longer in the treatment group compared to the control group. (2) During puberty, there were no significant differences in height growth between the treated and untreated groups. (3) The duration of GH treatment showed a significant negative correlation with the age at onset of gonadal development and the age at menarche in females within the treatment group. CONCLUSION: GH treatment does not seem to accelerate the onset of puberty but may extend its duration, without significantly impacting height growth during puberty. Additionally, longer GH treatment duration is linked to earlier gonadal development and menarche in females.

RESUMO

BACKGROUND: Recombinant human growth hormone (rhGH) therapy is beneficial for children with Prader-Willi syndrome (PWS) in improving short stature and metabolism, but the effect of early rhGH treatment on respiratory and sleep parameters for PWS children under three years old remains elusive. Thus, this study aimed to investigate the impact of rhGH treatment on sleep-related breathing disorders (SRBDs) for toddlers with PWS. METHODS: A total of 17 age-matched PWS patients receiving rhGH treatment (rhGH group) and 17 control individuals not receiving rhGH treatment (non-rhGH group) were recruited for this study between October 2018 and January 2023. Data related to polysomnography-polygraphy (PSG) and serum levels of insulin-like growth factor (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) were collected. RESULTS: The mean age in the rhGH group was 20.76 ± 9.22 months, which was comparable to that of the non-rhGH group (25.23 ± 13.81 months). The demographic and anthropometric parameters were similar across the two groups after 52 weeks of treatment. Administration of rhGH to toddlers did not exert adverse effects on the obstructive apnea-hypopnea index (OAHI), central apnea index (CAI), oxygen desaturation index (ODI), mean percutaneous oxygen saturation (SpO2), lowest SpO2, duration when SpO2 is lower than 90%, or proportion of the patients with SpO2 lower than 90%. Furthermore, the increased IGF-1 z-score and IGFBP-3 level did not worsen SRBDs. CONCLUSION: Treatment with rhGH for 52 weeks on young toddlers with PWS showed no deleterious effects on SRBDs. This shed more light on the importance of initiating rhGH therapy early in PWS patients.

RESUMO

Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria Abstract: Objective: The suppression of physiological puberty using puberty-blocking pharmacological agents (PB) and prescribing cross-sex hormones (CSH) to minors with gender dysphoria (GD) is a current matter of discussion, and in some cases, PB and CSH are used in clinical practice for this particular population. Two systematic reviews (one on PB, one on CSH treatment) by the British National Institute for Clinical Excellence (NICE) from 2020 indicated no clear clinical benefit of such treatments regarding critical outcome variables. In particular, these two systematic NICE reviews on the use of PB and CSH in minors with GD detected no clear improvements of GD symptoms. Moreover, the overall scientific quality of the available evidence, as discussed within the above-mentioned two NICE reviews, was classified as "very low certainty" regarding modified GRADE criteria. Method: The present systematic review presents an updated literature search on this particular topic (use of PB and CSH in minors with GD) following NICE principles and PICO criteria for all relevant new original research studies published since the release of the two above-mentioned NICE reviews (updated literature search period was July 2020-August 2023). Results: The newly conducted literature search revealed no newly published original studies targeting NICE-defined critical and important outcomes and the related use of PB in minors with GD following PICO criteria. For CSH treatment, we found two new studies that met PICO criteria, but these particular two studies had low participant numbers, yielded no significant additional clear evidence for specific and clearly beneficial effects of CSH in minors with GD, and could be classified as "low certainty" tfollowing modified GRADE criteria. Conclusions: The currently available studies on the use of PB and CSH in minors with GD have significant conceptual and methodological flaws. The available evidence on the use of PB and CSH in minors with GD is very limited and based on only a few studies with small numbers, and these studies have problematic methodology and quality. There also is a lack of adequate and meaningful long-term studies. Current evidence doesn't suggest that GD symptoms and mental health significantly improve when PB or CSH are used in minors with GD. Psychotherapeutic interventions to address and reduce the experienced burden can become relevant in children and adolescents with GD. If the decision to use PB and/or CSH is made on an individual case-by-case basis and after a complete and thorough mental health assessment, potential treatment of possibly co-occurring mental health problems as well as after a thoroughly conducted and carefully executed individual risk-benefit evaluation, doing so as part of clinical studies or research projects, as currently done in England, can be of value in terms of generation of new research data.

RESUMO

KEY MESSAGE: This review summarized how TFs function independently or in response to environmental factors to regulate terpenoid biosynthesis via fine-tuning the expression of rate-limiting enzymes. Terpenoids are derived from various species and sources. They are essential for interacting with the environment and defense mechanisms, such as antimicrobial, antifungal, antiviral, and antiparasitic properties. Almost all terpenoids have high medicinal value and economic performance. Recently, the control of enzyme genes on terpenoid biosynthesis has received a great deal of attention, but transcriptional factors regulatory network on terpenoid biosynthesis and accumulation has yet to get a thorough review. Transcription factors function as activators or suppressors independently or in response to environmental stimuli, fine-tuning terpenoid accumulation through regulating rate-limiting enzyme expression. This study investigates the advancements in transcription factors related to terpenoid biosynthesis and systematically summarizes previous works on the specific mechanisms of transcription factors that regulate terpenoid biosynthesis via hormone signal-transcription regulatory networks in plants. This will help us to better comprehend the regulatory network of terpenoid biosynthesis and build the groundwork for terpenoid development and effective utilization.

RESUMO

BACKGROUND: Gender minority individuals, on average, experience higher rates of mental health problems. Mounting work suggests that gender minority stress (GMS) contributes to mental health outcomes in transgender/gender-nonconforming individuals. AIM: We assessed whether GMS decreased in transgender people after initiating gender-affirming hormone therapy (GAHT), and we identified social predictors and hormonal associations for GMS at 2 time points. METHODS: GMS was surveyed through self-report questionnaires tapping into proximal and distal stressors and coping constructs following the minority stress framework. Eighty-five transgender persons wishing to undertake hormonal interventions were assessed prospectively at start of GAHT and after 7.7 ± 3.5 months (mean ± SD). Sixty-five cisgender persons served as a control group. OUTCOMES: (1) Proximal stressors were surveyed by the Beck Depression Inventory II, State-Trait Anxiety Inventory, Scale for Suicide Ideation, Suicidal Thoughts/Attempts, Stigma Consciousness Questionnaire, and Perceived Stress Scale; (2) distal stressors by the Everyday Discrimination Scale; and (3) coping constructs by the Resilience Scale, social network, social standing, and Marlowe Crowne Social Desirability Scale. RESULTS: Transgender people experienced higher rates of proximal stressors (Beck Depression Inventory II, State-Trait Anxiety Inventory, Scale for Suicide Ideation, Suicidal Thoughts/Attempts, Perceived Stress Scale) and had lower protective factors (social standing) prior to and during GAHT than cisgender people. Social network and resilience were lower in transgender people relative to cisgender peers only at baseline. Prospectively, decreasing trait anxiety was observed in transgender people. Social factors were adequate predictors of multiple GMS constructs. Specifically, a major role for social network emerged. As for hormonal associations, only serum estradiol levels in transgender women with GAHT were negatively associated with trait anxiety and suicidal thoughts/attempts but positively with resilience and social desirability. CLINICAL IMPLICATIONS: Stimulating a social environment supportive of diverse identities, particularly by investing in social networks as a resource for resilience, is likely to alleviate GMS. STRENGTHS AND LIMITATIONS: Longer duration of interventions with sex steroid treatment, with continued resilience-enhancing strategies, is needed to observe further alleviation of GMS in transgender persons. Also, objective and subjective GMS identification with heteronormative attitudes and beliefs should be surveyed for good measure when assessing GMS. CONCLUSION: Transgender people experienced more GMS throughout study visits than cisgender people did. With a relatively short period of GAHT, some significant changes in and predictors for experienced GMS emerged.

RESUMO

Idiopathic short stature (ISS) accounts for more than 70% of childhood short stature cases, with an undefined etiology and pathogenesis, leading to limited treatment. However, recent studies have shown that intestinal microbiota may be associated with ISS. This study aimed to characterize the intestinal microbiota in children with ISS, effect of treatment with growth hormones, and association between specific bacterial species and ISS. This study enrolled 55 children, comprising 40 diagnosed with ISS at Jinhua Hospital, Zhejiang University, and 15 healthy controls. The subjects with ISS were divided into the untreated ISS group (UISS group, 22 children who had not been treated with recombinant human growth hormone [rhGH]), treated ISS group (TISS group, 18 children treated with rhGH for 1 year), and control group (NC group, 15 healthy children). High-throughput sequencing was used to determine the intestinal microbiota characteristics. Higher abundances of Bacteroides, Prevotella, Alistipes, Parabacteroides, Agathobacter and Roseburia were found in the UISS and TISS groups than in the control group, whereas Bifidobacterium, Subdoligranulum, and Romboutsia were less abundant. The composition of intestinal microbiota in the UISS and TISS groups was almost identical, except for Prevotella. The TISS group had significantly lower levels of Prevotella than did the UISS group, which were closer to those of the NC group. Receiver operating characteristic curve analysis revealed that the abundances of Prevotella, Bifidobacterium, Bacteroides, and Subdoligranulum were effective in differentiating between the UISS and NC groups. CONCLUSION: Alterations in intestinal microbiota may be associated with ISS. Specific bacterial species, such as Prevotella, may be potential diagnostic markers for ISS. WHAT IS KNOWN: • ISS is associated with the GH-IGF-1 axis. • Recent studies indicated an association between the GH-IGF-1 axis and intestinal microbiota. WHAT IS NEW: • Children with ISS showed alterations in intestinal microbiota, with a relative increase in the abundance of gut inflammation-related bacteria. • The relative abundances of Prevotella, Bacteroides, Bifidobacterium, and Subdoligranulum may serve as potential diagnostic markers.

RESUMO

PURPOSE: Many issues still remain unresolved in the management of pubertal patients with gender incongruence (GI). The aim of this review is to discuss the main aspects of the treatment of these patients to provide a practical approach for clinicians. METHODS: A comprehensive literature search within PubMed was performed to provide updates of available evidence regarding the impact on bioethical, medical and fertility issues in gender incongruence during transition age. RESULTS: Gender Affirming Hormone Treatment (GAHT) and Gender Affirming Surgery (GAS) can induce unsatisfaction with change, future regrets, and the risk of infertility. This raises ethical issues especially in the management of pubertal patients that remain unresolved. Therapy with GnRH analogues (GnRHa) is intended to delay puberty, so as to give the adolescent a longer period of time to decide whether to continue with the treatments. At the level of physical changes, this therapy may have an effect on bone mineralization and body composition; however, long-term longitudinal data are not yet available. An important feature related to the use of GnRHa is the risk of fertility. Gamete cryopreservation is the most established method of fertility preservation (FP) and should be counselled to transgender adolescents. However, these patients are not always interested in having biological children. CONCLUSION: Based on the current evidence, there is a need to conduct further research to clarify certain issues and to standardize clinical practice and improve counselling in transgender adolescent decision making and avoid regrets in the future.

RESUMO

Reverse transcription quantitative polymerase chain reaction (RT-qPCR) is an accurate method for quantifying gene expression levels. Choosing appropriate reference genes to normalize the data is essential for reducing errors. Gelsemium elegans is a highly poisonous but important medicinal plant used for analgesic and anti-swelling purposes. Gelsenicine is one of the vital active ingredients, and its biosynthesis pathway remains to be determined. In this study, G. elegans leaf tissue with and without the application of one of four hormones (SA, MeJA, ETH, and ABA) known to affect gelsenicine synthesis, was analyzed using ten candidate reference genes. The gene stability was evaluated using GeNorm, NormFinder, BestKeeper, ∆CT, and RefFinder. The results showed that the optimal stable reference genes varied among the different treatments and that at least two reference genes were required for accurate quantification. The expression patterns of 15 genes related to the gelsenicine upstream biosynthesis pathway was determined by RT-qPCR using the relevant reference genes identified. Three genes 8-HGO, LAMT, and STR, were found to have a strong correlation with the amount of gelsenicine measured in the different samples. This research is the first study to examine the reference genes of G. elegans under different hormone treatments and will be useful for future molecular analyses of this medically important plant species.
