Review
As a type of lytic cell death driven by unrestricted lipid peroxidation and subsequent plasma membrane damage, ferroptosis occurs and develops because of sophisticated signals and regulatory mechanisms. The reactive oxygen species (ROS) used to initiate ferroptosis come from a variety of sources, including iron-mediated Fenton reactions, mitochondrial ROS, and membrane-associated ROS driven by the NOX protein family. Polyunsaturated fatty acid-containing phospholipids are the main substrates of lipid peroxidation in ferroptosis, which is positively regulated by enzymes, such as ACSL4, LPCAT3, ALOXs, or POR. Selective activation of autophagic degradation pathways promotes ferroptosis by increasing iron accumulation to cause lipid peroxidation. In contrast, system xc -glutathione-GPX4 axis plays a central role in limiting lipid peroxidation, although other antioxidants (such as coenzyme Q10 and tetrahydrobiopterin) can also inhibit ferroptosis. A main nuclear mechanism of cell defense against ferroptosis is the activation of the NFE2L2-dependent antioxidant response by transcriptionally upregulating the expression of antioxidants or cytoprotective genes. Additionally, the membrane damage caused by ferroptotic stimulus can be repaired by ESCRT-III-dependent membrane scission machinery. In this review, we summarize recent progress in understanding the signaling pathways and defense mechanisms of ferroptosis.

Review
The minority stress model has been influential in guiding research on sexual and gender minority health and well-being in psychology and related social and health sciences. Minority stress has theoretical roots in psychology, sociology, public health, and social welfare. Meyer provided the first integrative articulation of minority stress in 2003 as an explanatory theory aimed at understanding the social, psychological, and structural factors accounting for mental health inequalities facing sexual minority populations. This article reviews developments in minority stress theory over the past two decades, focusing on critiques, applications, and reflections on its continued relevance in the context of rapidly changing social and policy contexts.

Review
In line with increasing numbers of transgender (trans) and gender nonbinary people requesting hormone treatment, the body of available research is expanding. More clinical research groups are presenting data, and the numbers of participants in these studies are rising. Many previous review papers have focused on all available data, as these were scarce, but a more recent literature review is timely. Hormonal regimens have changed over time, and older data may be less relevant for today's practice. In recent literature, we have found that even though mental health problems are more prevalent in trans people compared to cisgender people, less psychological difficulties occur, and life satisfaction increases with gender-affirming hormone treatment (GAHT) for those who feel this is a necessity. With GAHT, body composition and contours change towards the affirmed sex. Studies in bone health are reassuring, but special attention is needed for adolescent and adult trans women, aiming at adequate dosage of hormonal supplementation and stimulating therapy compliance. Existing epidemiological data suggest that the use of (certain) estrogens in trans women induces an increased risk of myocardial infarction and stroke, the reason that lifestyle management can be an integral part of trans health care. The observed cancer risk in trans people does not exceed the known cancer-risk differences between men and women. Now it is time to integrate the mostly reassuring data, to leave the overly cautious approach behind, to not copy the same research questions repeatedly, and to focus on longer follow-up data with larger cohorts.

: Research has consistently reported gender differences in mental health, but studies on differences in psychological well-being between women and men have not yielded conclusive results. The aim of this study was to examine the relevance of gender to the psychological well-being of adult individuals. A cross-sectional study with a sample of 1700 men and 1700 women from the general Spanish population was conducted. Their ages ranged from 21 to 64 years, and they were assessed with Ryff's Psychological Well-Being Scales and the Bem Sex Role Inventory. : Men scored higher than women in self-acceptance and autonomy, and women scored higher than men in personal growth and positive relations with others. The most relevant variable in the psychological well-being of both women and men was high masculinity. Other relevant variables in women's well-being were high femininity, not having a manual occupation, not being homemakers, and professional occupation. Men´s well-being also was higher in professional men and in men with a skilled non-manual occupation, men with high femininity and men who were not single, divorced or widowed. : Adherence to traditional gender roles is relevant to the psychological well-being of women and men, and women and men whose self-concept includes both masculine-instrumental and feminine-expressive characteristics have greater well-being.

Gender transition is undertaken to improve the well-being of people suffering from gender dysphoria. However, some have argued that the evidence supporting medical interventions for gender transition (e.g., hormonal therapies and surgery) is weak and inconclusive, and an increasing number of people have come forward recently to share their experiences of transition regret and detransition. In this essay, I discuss emerging clinical and research issues related to transition regret and detransition with the aim of arming clinicians with the latest information so they can support patients navigating the challenges of regret and detransition. I begin by describing recent changes in the epidemiology of gender dysphoria, conceptualization of transgender identification, and models of care. I then discuss the potential impact of these changes on regret and detransition; the prevalence of desistance, regret, and detransition; reasons for detransition; and medical and mental healthcare needs of detransitioners. Although recent data have shed light on a complex range of experiences that lead people to detransition, research remains very much in its infancy. Little is known about the medical and mental healthcare needs of these patients, and there is currently no guidance on best practices for clinicians involved in their care. Moreover, the term detransition can hold a wide array of possible meanings for transgender-identifying people, detransitioners, and researchers, leading to inconsistences in its usage. Moving forward, minimizing harm will require conducting robust research, challenging fundamental assumptions, scrutinizing of practice patterns, and embracing debate.

Review
The COVID-19 pandemic has had a wide range of negative physical and mental impacts. This review begins with a theoretical explanation of the psychological defense mechanisms used to deal with the pandemic. It then discusses different categories of defense mechanisms and their roles in managing the impacts of psychological distress. The aim of this review is to highlight the various psychological defense mechanisms individuals use to deal with the pandemic and to discuss how adjustment mechanisms can protect individuals from internal and external threats by shielding the integrity of the ego (the mind) and helping individuals maintain their self-schema.

Some people, including minors, have a gender identity that does not correspond to the sex assigned at birth. They are known as trans* people, which is an umbrella term that encompasses transgender, transsexual, and other identities not conforming to the assigned gender. Healthcare units for trans* minors require multidisciplinary working, undertaken by personnel expert in gender identity, enabling, when requested, interventions for the minor and their social-familial environment, in an individualized and flexible way during the gender affirmation path. This service model also includes hormonal treatments tailored as much as possible to the individual's needs, beyond the dichotomic goals of a traditional binary model. This guide addresses the general aspects of professional care of trans* minors and presents the current evidence-based protocol of hormonal treatments for trans* and non-binary adolescents. In addition, it details key aspects related to expected body changes and their possible side effects, as well as prior counselling about fertility preservation.

Review
Gender dysphoria (GD) describes individuals for whom the native sex and expressed gender are not coincident and most of them self-identify as transgender women or men. It has been shown that genetic factors play an important role in GD and the presence of specific genetic variants in candidate genes could be correlated. On the other hand, twins studies have estimated its heritability. In this review, we collect and report the available data obtained by different molecular genetic studies.

Transgender healthcare faces a dilemma. On the one hand, access to certain medical interventions, including hormone treatments or surgeries, where desired, may be beneficial or even vital for some gender dysphoric trans people. But on the other hand, access to medical interventions typically requires a diagnosis, which, in turn, seems to imply the existence of a pathological state-something that many transgender people reject as a false and stigmatizing characterization of their experience or identity. In this paper we argue that developments from the human enhancement debate can help clarify or resolve some of the conceptual and ethical entanglements arising from the apparent conflict between seeking medicine while not necessarily suffering from a pathology or disorder. Specifically, we focus on the welfarist account of human enhancement and argue it can provide a useful conceptual framework for thinking about some of the more contentious disagreements about access to transgender healthcare services.
