Objective: This review synthesizes qualitative research about the experiences of parental caregivers enhancing their children's health after making the decision to not vaccinate their preschool children. This review aims to help health care providers understand the parental work involved in caring for under-vaccinated or unvaccinated children.

Introduction: Much of the current qualitative research literature about parents who are vaccine-hesitant or who decide not to vaccinate their children focuses on parental perceptions about the safety and efficacy of vaccines and decision-making.

The social contexts of transgender and gender-diverse (TGD) older adults remain under-examined. In this qualitative study, which involved six virtual focus groups with a total of 21 participants inclusive of TGD adults ages 50+, service providers, and community advocates, we sought to examine the healthcare and social service experiences and needs of TGD older adults in Canada. Drawing theoretically on critical gerontology and intersectionality, and methodologically on interpretive description, we examined the perspectives of different participant groups to develop insight into TGD older adults' issues and priorities in the context of their engagements with systems of care.

Article Synopsis
  • Young people today are increasingly identifying as gender-diverse, with adolescents being the fastest-growing group seeking gender-affirming healthcare.
  • There is significant debate and legislative restrictions surrounding gender-affirming healthcare, with some individuals equating it to "gay conversion therapy."
  • The commentary argues that gender-affirming healthcare is distinct from conversion therapy and suggests that acknowledging the complexities of sexuality and gender could improve these healthcare services.

Advocates and researchers have made myriad recommendations to guide policy actors in stopping conversion therapy. This commentary extends these recommendations by identifying core challenges that policy actors face with interventions that solely focus on conversion therapy. Conversion therapy exists because of pervasive social values and beliefs that devalue, erase and stigmatize Two-Spirit, lesbian, gay, bisexual, transgender, queer and other sexual and gender minority (2SLGBTQ+) people, in turn, creating a supply and demand market.

Immunotherapy is a rapidly evolving field, with many models attempting to describe its impact on the immune system, especially when paired with radiotherapy. Tumor response to this combination involves a complex spatiotemporal dynamic which makes either clinical or pre-clinical in vivo investigation across the resulting extensive solution space extremely difficult. In this review, several in silico models of the interaction between radiotherapy, immunotherapy, and the patient's immune system are examined.

Article Synopsis
  • - The study explored the prevalence and reasons for stopping gender-affirming medical treatment (GAMT) among transgender and gender-diverse youth in Canada and the U.S., using an online survey of individuals aged 15-29.
  • - Out of 3,937 participants, 16.8% who started GAMT reported discontinuing it, with health concerns, changing gender identity, and costs being the main reasons, while 37.2% wished they hadn't stopped.
  • - The findings indicate a need for more research to understand the factors influencing discontinuation of GAMT, as many participants who stopped still identified as transgender or gender-diverse.

Article Synopsis
  • Plant growth relies on both internal and external signals that regulate cell division, elongation, and wall thickening, with mechanical forces playing a crucial role in this process.
  • The study focuses on a bZIP transcription factor called SWIZ, which is involved in grass plants’ response to mechanical touch, leading to changes like reduced stem height and increased diameter.
  • Activation of touch-responsive genes was observed in roots after mechanostimulation, highlighting the unique role of SWIZ in regulating gene expression and providing new insights into how grasses perceive and respond to mechanical stimuli.

Background: Those who detransition have received increased public and scholarly attention and their narratives are often presented as evidence of limitations with contemporary gender-affirming care practices. However, there are scant empirical studies about how this population experienced their own process of gaining access to gender-affirming medical/surgical interventions, or their recommendations for care practice.

Aims: To qualitatively explore the care experiences and perspectives of individuals who discontinued or reversed their gender transitions (referred to as detransition).

Increasingly, applied social scientists and clinicians recognize the value of engaging transgender and gender-diverse (TGD) people, particularly TGD individuals with lived experience as care recipients (peers), to inform the provision of gender-affirming care. Despite this trend, few researchers have systematically examined how this group can contribute to and enhance the development and delivery of interventions intended to affirm gender diversity. In this article, we address limitations in the literature by drawing on a secondary analysis of qualitative data - originally collected to examine the peer support experiences of TGD individuals - to explore the potential that TGD peers hold for elevating gender-affirming care.

Emerging evidence suggests that transgender individuals are more likely than cisgender peers to receive a diagnosis with a primary mental disorder. Attributions of madness, though, may serve the social function of dismissing and discrediting transgender individual's self-perceptions. The narratives of individuals who stop or reverse an initial gender transition who also identify as living with mental health conditions can sometimes amplify these socio-political discourses about transgender people.

Introduction: Cancer is an enormous public health challenge in the United States and around the world. Early detection through screening can identify cancer when it is most treatable and can result in greater survival rates; however, racial and ethnic disparities in breast and cervical screening result in late diagnosis and a higher risk of poor outcomes and death for women of color.

Purpose: The purpose of this study was to examine barriers that a diverse sample of women in Rhode Island face related to breast and cervical cancer screening, as well as motivators that encourage women to obtain screening services.

Background: Since the onset of the COVID-19 pandemic in March 2020 in Canada, the availability of sexual health services including sexually transmitted and blood-borne infection (STBBI) testing has been negatively impacted in the province of Ontario due to their designation as "non-essential" health services. As a result, many individuals wanting to access sexual healthcare continued to have unmet sexual health needs throughout the pandemic. In response to this, sexual health service providers have adopted alternative models of testing, such as virtual interventions and self-sampling/testing.

Purpose: The COVID-19 pandemic presented new barriers and exacerbated existing inequities for physician scholars. While COVID-19's impact on academic productivity among women has received attention, the pandemic may have posed additional challenges for scholars from a wider range of equity-deserving groups, including those who hold multiple equity-deserving identities. To examine this concern, the authors conducted a scoping review of the literature through an intersectionality lens.

Trans masculine, two-spirit, and non-binary people who are gay, bisexual or otherwise have sex with men (TGBM) are under-tested for sexually transmitted infections (STI) and may face complex, intersectional barriers that prevent them from accessing STI testing. As part of a study on gay, bisexual and other men who have sex with men's (GBM) experiences of current STI testing systems in Ontario, Canada, this paper reports on the findings from TGBM participants' experiences with in-person STI testing in a range of venues (i.e.

Importance: Medical education, research, and clinical guidelines are available to support the initiation of gender-affirming care for transgender and nonbinary people. By contrast, little is known about the clinical experiences of those who discontinue or seek to reverse gender-affirming medical or surgical interventions due to a change in gender identity, often referred to as detransition.

Objective: To examine the physical and mental health experiences of people who initiated medical or surgical detransition to inform clinical practice.

Background: We conducted an investigator-initiated, phase I trial of vincristine sulfate liposomal injection (VSLI) in combination with bendamustine and rituximab (BR) for indolent B-cell (BCL) or mantle cell lymphoma.

Methods: Participants received 6 cycles of standard BR with VSLI at patient-specific dose determined by the Escalation with Overdose Control (EWOC) model targeting 33% probability of dose-limiting toxicity (DLT). Maximum tolerated dose (MTD) was the primary endpoint; secondary endpoints included rates of adverse events (AEs), overall response rate (ORR), and complete response (CR).

Gatekeeping refers to clinicians' strict application of eligibility criteria to determine a trans patient's "fitness" to engage in medical transition, resulting in significant barriers to gender-affirming care. Gatekeeping often uses "mental readiness" as a prerequisite to medical transition, which contributes to patient distress and systemic discrimination. Changing international trans health guidelines (the new World Professional Association for Transgender Health Standards of Care version 8) recommends clinicians shift from a gatekeeping model towards an informed consent model, which improves access to care.
