Exploring Gender Diversity in Transgender and Non-Binary Adults Accessing a Specialized Service in Italy.

In Italy, studies investigating gender identity and expression in gender non-conforming adults are lacking, as well as data regarding the non-binary population. The present study aimed at dimensionally exploring how transgender and non-binary Italian adults identify and express their gender. The Gender Diversity Questionnaire (GDQ) was administered to a sample of 112 adult subjects aged 18-60 years accessing a gender-specialized service in Rome. The majority of the participants were aged 18-24 years (53.6%), whereas fewer subjects were aged 25-35 years (32%) and 35 years and older (14.3%). Most participants (83.9%) identified themselves as trans binary, while the remaining (16.1%) identified as non-binary. Trans binary participants reported a stable gender identity, whereas non-binary participants reported a more fluid gender identity over time and across contexts. Younger subjects recognized the use of chosen names, pronouns, and clothes as important for their gender expression, whereas older subjects attributed more importance to physical appearance and emotions. Differences regarding gender-affirmative interventions emerged between non-binary and transbinary participants. Findings evidence that gender non-conforming adults accessing gender-specialized services have unique needs and features, thus it is essential to shed light on this population by providing greater visibility and recognition.

Gender Identity and Non-Binary Presentations in Adolescents Attending Two Specialized Services in Italy.

BACKGROUND: Recently, the variability and heterogeneity of gender presentations in transgender youths have gained significant attention worldwide. Alongside this, specialized gender services have reported an increase in referrals of youths reporting non-binary identities. In Italy, studies investigating gender identity and expression in gender non-conforming youths are lacking, as are data regarding the non-binary population. AIM: The present study aimed at dimensionally exploring how transgender and non-binary Italian adolescents identify and express their gender. OUTCOMES: Gender expression in trans binary youths and non-binary youths. METHODS: The Gender Diversity Questionnaire (GDQ; Twist & de Graaf, 2019) was used to investigate gender identity, gender fluidity, and gender expression in a sample of 125 adolescent patients from the Gender Identity Development Service (SAIFIP) in Rome and the Gender Incongruence Unit of the Careggi Hospital in Florence, between April 2019-June 2021. RESULTS: The majority of participants (74.4%) identified as trans* binary and the remaining (25.6%) participants identified as non-binary. Trans binary participants reported a stable gender identity, whereas non-binary participants reported a more fluid gender identity across time and contexts. Almost all participants rated external appearance as important to their gender expression, yet trans binary participants attributed more importance to the body in this respect. Body discomfort and pubertal stage emerged as the most influential factors in participants' experiences of gender. Participants who were assigned male at birth expressed significantly more desire for puberty blockers, whereas those who were assigned female at birth had a stronger desire to engage in breast/chest surgery. Non-binary participants sought different medical interventions relative to trans binary participants. CLINICAL IMPLICATIONS: These results may be useful for clinicians working with transgender youths as they provide awareness regarding the features of young people who identify within and outside of binary constructions of gender. STRENGTHS & LIMITATIONS: This study provides useful data in gaining insight into understanding the variety of experiences and challenges of gender non-conforming youths. However as the sample was recruited from specialized services, it may not represent the entire gender non-conforming population in Italy. CONCLUSION: The results describe the range of gender identities and expressions among gender non-conforming youths attending gender specialized services in Italy, thereby improving our understanding of the variety of identities experienced and the specific medical needs of both trans binary and non-binary adolescents.

Benign catalysis with iron: unique selectivity in catalytic isomerization reactions of olefins.

The use of noble metal catalysts in homogeneous catalysis has been well established. Due to their price and limited availability, there is growing interest in the substitution of such precious metal complexes with readily available and bio-relevant catalysts. In particular, iron is a "rising star" in catalysis. Herein, we present a general and selective iron-catalyzed monoisomerization of olefins, which allows for the selective generation of 2-olefins. Typically, common metal complexes give mixtures of various internal olefins. Both bulk-scale terminal olefins and functionalized terminal olefins give the corresponding products under mild conditions in good to excellent yields. The proposed reaction mechanism was elucidated by in situ NMR studies and supported by DFT calculations and extended X-ray absorption fine structure (EXAFS) measurements.

Reversed-phase liquid chromatographic profile of free amino acids in strawberry-tree (Arbutus unedo L.) honey.

The typical profile of the free amino acids contained in strawberry-tree (Arbutus unedo L.) honey is reported for the first time. An optimized reversed-phase liquid chromatographic (RP-LC) method with phenyl isothiocyanate precolumn derivatization was used. Fourteen free amino acids were identified and quantified in 16 analytical samples. Proline (65.63%) was found to be the most abundant free amino acid, followed by glutamic acid (6.49%), arginine (5.21%), alanine (5.17%), and phenylalanine (4.97%). The total free amino acid content of strawberry-tree honey (average value, 436 mg/kg) was found to be low in comparison to amounts cited in the literature concerning unifloral honeys. The analytical method was optimized and fully validated in terms of detection and quantitation limits, precision (by testing repeatability and reproducibility), linearity, and bias (by means of recovery tests). The acceptability of the validation protocol results was verified using Horwitz's mathematical model and AOAC guidelines.

Palladium-catalyzed isomerization and hydroformylation of olefins.

A novel selective palladium catalyst system based on bidentate 2,2'-heteroarylarylphosphines and p-TsOH has been developed for hydroformylation reactions (see scheme). By applying optimal conditions good to excellent regioselectivity is obtained for the hydroformylation of aliphatic and aromatic olefins. It is shown that a low acid concentration is crucial for obtaining high degrees of the linear isomer.The palladium-catalyzed hydroformylation of 1-octene has been studied in the presence of different phosphines and acid cocatalysts. The best results are achieved in the presence of in situ-generated palladium complexes with bidentate phosphines. It is demonstrated that the acid concentration is a crucial factor for obtaining high linear selectivity. A novel optimized catalyst based on an arylheteroarylphosphine has been applied for hydroformylation of different aliphatic and aromatic olefins. Good activity and excellent selectivity towards the linear aldehydes is achieved.
