RESUMO
PURPOSE: Transgender adults face increasingly discriminatory laws/policies and prejudicial attitudes in many regions of the United States (US), yet research has neither quantified state-level transphobia using indicators of both, nor considered their collective association with transgender adults' psychological wellbeing, hindering the identification of this potential social determinant of transgender mental health inequity. METHODS: We therefore used factor analysis to develop a more comprehensive structural transphobia measure encompassing 29 indicators of transphobic laws/policies and attitudes at the state level, which we linked to individual-level mental health data from a large national sample of 27,279 transgender adults (ages 18-100) residing in 45 US states and the District of Columbia (DC). RESULTS: Controlling for individual- (i.e., demographics), interpersonal- (i.e., perceived discrimination), and state- (i.e., income inequality, religiosity) level covariates, transgender adults from US states with higher (vs. lower) levels of structural transphobia reported more severe past-month psychological distress and were more likely to endorse past-year and lifetime suicidal thoughts, plans, and attempts. CONCLUSION: Findings provide novel evidence that state-level transphobic laws/policies and attitudes collectively shape a range of important mental health outcomes among transgender adults in the US. Multilevel intervention strategies, such as affirming mental health treatments, provider-training interventions, and supportive legislation, are needed to address structural transphobia's multifaceted nature and negative mental health consequences.

Stigma refers to societally-deemed inferiority associated with a circumstance, behavior, status, or identity. It manifests internally, interpersonally, and structurally. Decades of research indicate that all forms of stigma are associated with heightened risk for mental health problems (e.g., depression, PTSD, suicidality) in stigmatized youth (i.e., children, adolescents, and young adults with one or more stigmatized identities, such as youth of Color and transgender youth). Notably, studies find that stigmatized youth living in places with high structural stigma - defined as laws/policies and norms/attitudes that hurt stigmatized people - have a harder time accessing mental health treatment and are less able to benefit from it. In order to reduce youth mental health inequities, it is imperative for our field to better understand, and ultimately address, stigma at each of these levels. To facilitate this endeavor, we briefly review research on stigma and youth mental health treatment, with an emphasis on structural stigma, and present three future directions for research in this area: (1) directly addressing stigma in treatment, (2) training therapists in culturally responsive care, and (3) structural interventions. We conclude with recommendations for best practices in broader mental health treatment research.

OBJECTIVE: Transgender adolescents experience adversity accessing mental healthcare, which is exacerbated by transgender-specific mental health provider shortages in the United States. Factors associated with variability in transgender-specific mental health provider availability across states - especially at the macro-social level - have yet to be identified, hindering efforts to address these shortages. To remedy this gap, we queried whether transgender-specific adolescent mental health provider availability varied by states' transgender-specific policy climate. METHOD: We quantified states' policy climate by factor-analyzing tallies of the presence/absence of 33 transgender-specific state laws/policies in six domains: parental/relationship recognition, nondiscrimination, education, healthcare, criminal justice, and identity documentation. We then tested whether states' transgender-specific policy climate was associated with rates of transgender-specific adolescent mental health providers - identified via Psychology Today - per transgender adolescent in all 50 states and the District of Columbia. RESULTS: Transgender-specific adolescent mental health provider availability was substantially lower in states with more restrictive laws/policies for transgender people (rate ratio = 0.65, 95% CI [0.52, 0.81], p = .00017), controlling for state-level conservatism, religiosity, and urbanicity. States' transgender-specific policy climate was unrelated to rates of adolescent Attention-Deficit/Hyperactivity Disorder-specialty providers, Oppositional Defiant Disorder-specialty providers, and youth mental health provider shortages broadly, providing evidence for result specificity. CONCLUSIONS: Transgender adolescents appear to have access to considerably fewer transgender-specific mental health providers in states with more restrictive laws/policies for transgender people, which may compound their already high mental health burden in these contexts. Intervention and policy efforts are needed to address these shortages, particularly in states with increasingly prohibitive laws/policies targeting transgender adolescents.
RESUMO
BACKGROUND: Vitiligo is an autoimmune disease in which cutaneous depigmentation occurs. Existing therapies are often inadequate. Prior reports have shown benefit of the Janus kinase (JAK) inhibitors. OBJECTIVE: To evaluate the efficacy of the JAK 1/3 inhibitor tofacitinib in the treatment of vitiligo. METHOD: This is a retrospective case series of 10 consecutive patients with vitiligo treated with tofacitinib. Severity of disease was assessed by body surface area of depigmentation. RESULTS: Ten consecutive patients were treated with tofacitinib. Five patients achieved some repigmentation at sites of either sunlight exposure or low-dose narrowband ultraviolet B phototherapy. Suction blister sampling revealed that the autoimmune response was inhibited during treatment in both responding and nonresponding lesions, suggesting that light rather than immunosuppression was primarily required for melanocyte regeneration. LIMITATIONS: Limitations include the small size of the study population, retrospective nature of the study, and lack of a control group. CONCLUSION: Treatment of vitiligo with JAK inhibitors appears to require light exposure. In contrast to treatment with phototherapy alone, repigmentation during treatment with JAK inhibitors may require only low-level light. Maintenance of repigmentation may be achieved with JAK inhibitor monotherapy. These results support a model wherein JAK inhibitors suppress T cell mediators of vitiligo and light exposure is necessary for stimulation of melanocyte regeneration.

Experience gained in the risk assessment (RA) of genetically engineered (GE) crops since their first experimental introductions in the early nineties, has increased the level of familiarity with these breeding methodologies and has motivated several agencies and expert groups worldwide to revisit the scientific criteria underlying the RA process. Along these lines, the need to engage in a scientific discussion for the case of GE crops transformed with similar constructs was recently identified in Argentina. In response to this need, the Argentine branch of the International Life Sciences Institute (ILSI Argentina) convened a tripartite working group to discuss a science-based evaluation approach for transformation events developed with genetic constructs which are identical or similar to those used in previously evaluated or approved GE crops. This discussion considered new transformation events within the same or different species and covered both environmental and food safety aspects. A construct similarity concept was defined, considering the biological function of the introduced genes. Factors like environmental and dietary exposure, familiarity with both the crop and the trait as well as the crop biology, were identified as key to inform a construct-based RA process.

BACKGROUND AND AIMS: Resveratrol, the most investigated dietary compound in studies aimed at linking wine consumption to human health, is an extremely minor component of this beverage and it is generally studied in vitro as the unconjugated aglycone at concentrations largely exceeding those found in the human circulatory system after dietary intake. Moreover, following intestinal absorption, trans-resveratrol and its glucoside, which are naturally present in wine and other food sources, are converted to sulphate and glucuronide metabolites. An estrogenic activity has previously been documented for resveratrol, yet nothing is known about the activity of its blood-circulating metabolic derivatives. METHODS AND RESULTS: Using a yeast two-hybrid detection system relying on the interaction between the ligand-binding domain of the human oestrogen receptors α and ß and the human coactivator Tif2, we have systematically examined the oestrogen agonist and antagonist activities of the two main resveratrol forms present in planta (trans-resveratrol and trans-resveratrol-3-O-glucoside) and of the three main metabolites found in human plasma (trans-resveratrol-3-O-sulphate, trans-resveratrol-3-O-glucuronide and trans-resveratrol-4'-O-glucuronide). Only resveratrol-3-O-sulphate was found to display a fairly strong and oestrogen receptor α-preferential antagonistic activity, which was confirmed in a human breast adenocarcinoma cell line containing a luciferase reporter gene under the control of an oestrogen-responsive promoter. CONCLUSIONS: We show, for the first time, that resveratrol-3-O-sulphate, but neither of its metabolites, is endowed with anti-estrogenic activity and how human metabolism of phenolic substances plays a pivotal role in modulating their biological effect.

Home cooking is an emerging strategy to improve nutrition; however, the literature lacks reports about patient expectations from culinary interventions. Personalized medicine utilizes knowledge about a person's genes; yet, behavioral factors, such as participant "readiness" to make a change, may also impact treatment preferences and outcomes. The purpose is to explore the expectations of participants in different stages of change from a home cooking intervention. Participants were recruited to a randomized controlled trial evaluating the impact of a home cooking intervention on weight. Stage of change assessed by a validated University of Rhode Island Change Assessment scale and expectations through an open-ended questionnaire. Sixteen (21%) participants were in the action stage of change, and 59 (79%) were in the contemplation stage. Participants from both groups shared similar expectations to achieve healthy eating and lifestyle goals and to adopt sustainable change. However, action group expectations also included expanding existing culinary knowledge and change of habits; the contemplation group expectations also included acquiring culinary knowledge, improving self-regulatory skills, and obtaining guidance and support. While action group participants were looking to expand existing knowledge and techniques, contemplation group participants were focusing on acquiring culinary knowledge and skills. This can potentially contribute to developing effective, personalized nutrition interventions.

Vitiligo is characterized by the development of depigmented macules and patches. Autoimmunity has been established as a factor in disease pathogenesis, leading to utilization of immunosuppressive agents. Topical immunosuppressants are commonly used; however, this treatment modality is often cumbersome and inefficient, as many patients have active disease with extensive body surface area involvement. Prompt and aggressive treatment of vitiligo is important, as this may prevent progression and improve quality of life. To meet these challenges and improve patient outcomes, interest in systemic therapies has grown. Currently, oral therapies are rarely prescribed, likely due to concerns with systemic side effects and unclear efficacy. This article provides a brief overview on the use of systemic agents in treating vitiligo in order to provide additional therapeutic options to clinicians.

The melanocyte-keratinocyte transplantation procedure (MKTP) treats stable and recalcitrant vitiligo. Despite careful selection of candidates based on clinical stability, the success of the procedure is unpredictable. The aim of our study was to define the immunological profile of stable vitiligo lesions undergoing MKTP and correlate them with clinical outcomes. We included 20 MKTP candidates with vitiligo and a patient with piebaldism as a control. Prior to MKTP, T-cell subsets and chemokines in the recipient skin were measured by flow cytometry and ELISA. During MKTP, melanocytes in the donor skin were quantified by flow cytometry. After MKTP, patients were followed for 12 months and repigmentation was assessed clinically and by ImageJ analysis of clinical photographs. Baseline immunologic biomarkers, duration of clinical stability, and transplanted melanocyte number were correlated to postsurgical repigmentation scores. CD8+ T cells were elevated in 43% of the clinically stable vitiligo lesions. CD8+ T-cell number negatively correlated with postsurgical repigmentation scores (r = -0.635, P = 0.002). Duration of clinical stability, skin chemokines, and transplanted melanocyte number did not influence postsurgical repigmentation. This study demonstrates that CD8+ T-cell number correlates negatively with success of postsurgical repigmentation and can be a biomarker to identify ideal surgical candidates.
RESUMO
TKIs long-term treatment in CML may lead to persistent adverse events (AEs) that can promote relevant morbidity and mortality. Consequently, TKIs dose reduction is often used to prevent AEs. However, data on its impact on successful treatment-free remission (TFR) are quite scarce. We conducted a retrospective study on the outcome of CML subjects who discontinued low-dose TKIs from 54 Italian hematology centers participating in the Campus CML network. Overall, 1.785 of 5.108 (35.0%) regularly followed CML patients were treated with low-dose TKIs, more frequently due to relevant comorbidities or AEs (1.288, 72.2%). TFR was attempted in 248 (13.9%) subjects, all but three while in deep molecular response (DMR). After a median follow-up of 24.9 months, 172 (69.4%) patients were still in TFR. TFR outcome was not influenced by gender, Sokal/ELTS risk scores, prior interferon, number and last type of TKI used prior to treatment cessation, DMR degree, reason for dose reduction or median TKIs duration. Conversely, TFR probability was significantly better in the absence of resistance to any prior TKI. In addition, patients with a longer DMR duration before TKI discontinuation (i.e., >6.8 years) and those with an e14a2 BCR::ABL1 transcript type showed a trend towards prolonged TFR. It should also be emphasized that only 30.6% of our cases suffered from molecular relapse, less than reported during full-dose TKI treatment. The use of low-dose TKIs does not appear to affect the likelihood of achieving a DMR and thus trying a treatment withdrawal, but might even promote the TFR rate.
RESUMO
Consequences of a spinal cord injury (SCI) entail much more than damage to the spinal cord. The lives of people with SCI, along with those around them, experience profound long-lasting changes in nearly every life domain. SCI is a physical (biological) injury that is inextricably combined with various psychological and social consequences. The objective of this review is to present psychosocial challenges following SCI through the biopsychosocial model, beginning with acknowledgement of the larger societal effects of ableism and stigma before addressing the many unique psychosocial aspects of living with SCI. Included in this review are qualitative studies and systematic reviews on current psychosocial outcomes and consequences. This paper attempts to structure this information by dividing it into the following sections: relationships and family; changes in finances and employment; issues related to the person's living situation; community reintegration; factors associated with mood and coping (e.g., depression, anxiety, substance use, and PTSD); self-harm behaviors (ranging from nonadherence to suicide); effects of traumatic brain injury; considerations regarding sexual health; aging with SCI; and concludes with a brief discussion about post-traumatic growth. Cultivating an understanding of the unique and interrelated psychosocial consequences of people living with SCI may help mitigate the psychosocial aftermath and serve as a reminder to providers to maintain a person-centered approach to care.
RESUMO
OBJECTIVE: To examine whether anti-Black cultural racism moderates the efficacy of psychotherapy interventions among youth. METHOD: A subset of studies from a previous meta-analysis of 5 decades of youth psychotherapy randomized controlled trials was analyzed. Studies were published in English between 1963 and 2017 and identified through a systematic search. The 194 studies (N = 14,081 participants; age range, 2-19) across 34 states comprised 2,678 effect sizes (ESs) measuring mental health problems (eg, depression) targeted by interventions. Anti-Black cultural racism was operationalized using a composite index of 31 items measuring explicit racial attitudes (obtained from publicly available sources, eg, General Social Survey) aggregated to the state level and linked to the meta-analytic database. Analyses were conducted with samples of majority-Black (ie, ≥50% Black) (n = 36 studies) and majority-White (n = 158 studies) youth. RESULTS: Two-level random-effects meta-regression analyses indicated that higher anti-Black cultural racism was associated with lower ESs for studies with majority-Black youth (ß = -0.2, 95% CI [-0.35, -0.04], p = .02) but was unrelated to ESs for studies with majority-White youth (ß = 0.0004, 95% CI [-0.03, 0.03], p = .98), controlling for relevant area-level covariates. In studies with majority-Black youth, mean ESs were significantly lower in states with the highest anti-Black cultural racism (>1 SD above the mean; Hedges' g = 0.19) compared with states with the lowest racism (<1 SD below the mean; Hedges' g = 0.60). CONCLUSION: Psychotherapies tested with samples of majority-Black youth were significantly less effective in states with higher (vs lower) levels of anti-Black cultural racism, suggesting that anti-Black cultural racism may be one contextual moderator of treatment effect heterogeneity.

Exposure during early development to chemicals with hormonal action may be associated with weight gain during adulthood because of altered body homeostasis. It is known that organotins affect adipose mass when exposure occurs during fetal development, although no knowledge of effects are available for exposures after birth. Here we show that the environmental organotin tributyltin chloride (TBT) exerts adipogenic action when peripubertal and sexually mature mice are exposed to the chemical. The duration and extent of these effects depend on the sex and on the dose of the compound, and the effects are relevant at doses close to the estimated human intake (0.5µg/kg). At higher doses (50-500µg/kg), TBT also activated estrogen receptors (ERs) in adipose cells in vitro and in vivo, based on results from acute and longitudinal studies in ERE/luciferase reporter mice. In 3T3-L1 cells (which have no ERs), transiently transfected with the ERE-dependent reporter plus or minus ERα or ERß, TBT (in a dose range of 1-100nM) directly targets each ER subtype in a receptor-specific manner through a direct mechanism mediated by ERα in undifferentiated preadipocytic cells and by ERß in differentiating adipocytes. The ER antagonist ICI-182,780 inhibits this effect. In summary, the results of this work suggest that TBT is adipogenic at all ages and in both sexes and that it might be an ER activator in fat cells. These findings might help to resolve the apparent paradox of an adipogenic chemical being also an estrogen receptor activator by showing that the two apparently opposite actions are separated by the different doses to which the organism is exposed.

The coronavirus pandemic enforced social restrictions with abrupt impacts on mental health and changes to health behaviors. From a randomized clinical trial, we assessed the impact of culinary education on home cooking practices, coping strategies and resiliency during the first wave of the COVID-19 pandemic (March/April 2020). Participants (n = 28) were aged 25-70 years with a BMI of 27.5-35 kg/m2. The intervention consisted of 12 weekly 30-min one-on-one telemedicine culinary coaching sessions. Coping strategies were assessed through the Brief Coping with Problems Experienced Inventory, and resiliency using the Brief Resilient Coping Scale. Home cooking practices were assessed through qualitative analysis. The average use of self-care as a coping strategy by the intervention group was 6.14 (1.66), compared to the control with 4.64 (1.69); p = 0.03. While more intervention participants had high (n = 5) and medium (n = 8) resiliency compared to controls (n = 4, n = 6, respectively), this difference was not significant (p = 0.33). Intervention participants reported using home cooking skills such as meal planning and time saving techniques during the pandemic. The key findings were that culinary coaching via telemedicine may be an effective intervention for teaching home cooking skills and promoting the use of self-care as a coping strategy during times of stress, including the COVID-19 pandemic.

Introduction: Schools have become a primary setting for providing mental health care to youths in the U.S. School-based interventions have proliferated, but their effects on mental health and academic outcomes remain understudied. In this study we will implement and evaluate the effects of a flexible multidiagnostic treatment called Modular Approach to Therapy for Children with Anxiety, Depression, Trauma, or Conduct Problems (MATCH) on students' mental health and academic outcomes. Methods and Analysis: This is an assessor-blind randomized controlled effectiveness trial conducted across five school districts. School clinicians are randomized to either MATCH or usual care (UC) treatment conditions. The target sample includes 168 youths (ages 7-14) referred for mental health services and presenting with elevated symptoms of anxiety, depression, trauma, and/or conduct problems. Clinicians randomly assigned to MATCH or UC treat the youths who are assigned to them through normal school referral procedures. The project will evaluate the effectiveness of MATCH compared to UC on youths' mental health and school related outcomes and assess whether changes in school outcomes are mediated by changes in youth mental health. Ethics and Dissemination: This study was approved by the Harvard University Institutional Review Board (IRB14-3365). We plan to publish the findings in peer-reviewed journals and present them at academic conferences. Clinical Trial Registration: ClinicalTrials.gov ID: NCT02877875. Registered on August 24, 2016.
RESUMO
Over 20 years of accumulated evidence has shown that the major female sex hormone 17ß-estradiol can enhance cognitive functioning. However, the utility of estradiol as a therapeutic cognitive enhancer is hindered by its unwanted peripheral effects (carcinogenic). Selective estrogen receptor modulators (SERMs) avoid the unwanted effects of estradiol by acting as estrogen receptor antagonists in some tissues such as breast and uterus, but as agonists in others such as bone, and are currently used for the treatment of osteoporosis. However, understanding of their actions in the brain are limited. The third generation SERM bazedoxifene has recently been FDA approved for clinical use with an improved biosafety profile. However, whether bazedoxifene can enter the brain and enhance cognition is unknown. Using mice, the current study aimed to explore if bazedoxifene can 1) cross the blood-brain barrier, 2) rescue ovariectomy-induced hippocampal-dependent spatial memory deficit, and 3) activate neural estrogen response element (ERE)-dependent gene transcription. Using liquid chromatography-mass spectrometry (LC-MS), we firstly demonstrate that a peripheral injection of bazedoxifene can enter the brain. Secondly, we show that an acute intraperitoneal injection of bazedoxifene can rescue ovariectomy-induced spatial memory deficits. And finally, using the ERE-luciferase reporter mouse, we show in vivo that bazedoxifene can activate the ERE in the brain. The evidence shown here suggest bazedoxifene could be a viable cognitive enhancer with promising clinical applicability.

INTRODUCTION: Suicide is a global problem and accurate assessment of risk for self-harm is critical. Even morally principled clinicians can manifest bias when assessing self-harm in patients with physical disabilities such as spinal cord injury (SCI). Assessment of self-harm is an obligation for health care clinicians and overestimating or underestimating risk may undermine a patient's trust in their care, possibly leading to less engagement, increased apathy about having an interest in living, and less adherence to healthy treatment options. CASE PRESENTATION: Introduces readers to three biases that can impact decision-making regarding a patient with a disability when assessing the patient's risk for self-harm: (1) ineffectual bias, (2) fragile friendliness bias, and (3) catastrophe bias. These preconceptions are derived from a mix of paternalism, projection, low expectations, pity, and infantilization. In this paper, we explain how each bias can affect clinical decision-making regarding diagnosis, treatment, prognosis, and prevention for patients with SCI within a common case scenario. Readers can employ personal reflection and potential self-application when they encounter individuals with SCI in and outside clinical settings. DISCUSSION: Unchecked biases toward the disabled and patients with SCI can undermine ethical caregiving. Biases are habits of mind and thoughtful clinical and education interventions can improve clinical practice. The literature on health care bias with other minority groups is instructive for investigating biases related to patients with disabilities, and especially for clinicians outside of rehabilitation medicine.

OBJECTIVE: Gender minority youth (i.e., children/adolescents whose gender identity and/or expression is inconsistent with their birth-assigned sex) experience elevated rates of emotional and behavioral problems relative to cisgender youth (who identify with their birth-assigned sex), which are not intrinsic to gender identity but attributable to unique minority stressors. Although empirically supported treatments have proven effective in treating these mental health concerns generally, randomized controlled trials have not examined effects for gender minority youth. METHOD: To address this gap, we pooled data from clinically referred youth (N = 432; M(SD)age = 10.6(2.2); 55.1% White) assigned to empirically supported treatment conditions across four previous randomized controlled trials of modular psychotherapy. A proxy indicator of gender identity (i.e., youth's wish to be the opposite sex) was used to classify gender minority (n = 64) and cisgender (n = 368) youth. Youth- and caregiver-reported pretreatment internalizing and externalizing problems, treatment effectiveness on these domains, and treatment acceptability were compared across groups. RESULTS: Gender minority youth reported more severe pretreatment internalizing and externalizing problems compared to cisgender youth; in contrast, their caregivers reported less severe problems. Although treatment was equally effective for both groups on most outcomes, gender minority youth's caregiver-reported externalizing problems improved more slowly and less reliably, and their self-reported internalizing problems were more likely to remain clinically elevated. Furthermore, gender minority youth reported lower treatment satisfaction. CONCLUSIONS: While findings suggest that empirically supported treatments may effectively address many mental health problems for gender minority youth, they also underscore the need for treatment enhancements that improve acceptability and outcomes.

Group B streptococci (GBS), a leading cause of neonatal sepsis and meningitis, are transferred to neonates from colonized mothers during childbirth. Prior studies using multilocus sequence typing (MLST) have found specific GBS clones (e.g., sequence type 17 [ST-17]) to be associated with neonatal disease in several geographic locations. Few population-based studies, however, have been conducted to determine the frequency of disease caused by specific GBS clones. MLST was used to assess the genetic diversity of 192 GBS strains from neonates and young children identified by population-based surveillance in Alberta, Canada, from 1993 to 2002. Comparisons were made to 232 GBS strains collected from colonized pregnant women, and all strains were characterized for one of nine capsule (cps) genotypes. A total of 47 STs were identified, and more than 80% of GBS strains were represented by 7 STs that have been shown to predominate in other populations. ST-17 and ST-19 were more prevalent in strains causing early onset disease (EOD) and late onset disease (LOD) than from pregnant women, whereas STs 1, 12, and 23 were more common in pregnant women. In addition, ST-17 strains and close relatives more frequently caused meningitis than sepsis and LOD versus EOD in this population of neonates. Further research is required to better understand why strains belonging to the ST-17 phylogenetic lineage are more likely to cause both LOD and meningitis and may provide clues into the pathogenesis of these conditions.

Incubation of rat cerebral cortical slices with the beta-adrenergic agonist isoproterenol causes an increase in alpha 2-adrenergic receptor binding in addition to a decrease in beta-adrenergic receptor binding. The effects are rapid and reversible, show a parallel time course, and are blocked by sotalol, a beta-adrenergic receptor antagonist. The beta-mediated regulation of alpha 2-receptor sensitivity at brain norepinephrine synapses may be a mechanism for the homeostatic control of central noradrenergic activity.
