RESUMO

The desire to die by suicide has been linked with interpersonal difficulties and impeded clinical outcomes. Despite the emphasis on the therapeutic relationship in clinical guidelines for working with suicidal clients, little is known about how suicidal clients' interpersonal difficulties manifest in clinical contexts. Additionally, there is limited understanding of the therapeutic relationship in single-session suicidal crisis contexts. Our aim was to examine the trajectory of the therapeutic bond in mediating clients' suicidal desire and outcome in single-session suicidal crisis intervention. Single-session online text-based crisis intervention sessions (N = 354; Mage = 29.43, SD = 9.15; 64.5% women) were coded for suicidal desire, therapeutic bond (each quarter), and outcome. We examined the proposed sequential mediating model (suicidal desire to early bond to bond change to outcome) using structural equation modeling. The proposed sequential mediation model fits the data well, χ2(11) = 22.030, p = .0241, root-mean-square error of approximation = .053, 90% CI [.019, .085], comparative fit index = .983, Tucker-Lewis index = .977, and was a better fit than several alternative models. Further, the indirect effect from suicidal desire to outcome through early bond and bond change was significant (b = -0.474, 99% CI [-0.782, -0.203]). Our findings indicate that therapeutic bonds were beneficial for clients with elevated suicidal desire-and-elevated suicidal desire was negatively associated with therapeutic bonds. These findings highlight the importance of training clinicians to navigate the unique challenges of developing therapeutic bonds with acutely suicidal clients.

RESUMO

Sexual and gender minorities (SGM) experience higher rates of psychological distress and seek psychotherapy at higher rates compared to their heterosexual and cisgender counterparts. However, few therapists are trained on how to provide effective psychotherapy with SGM clients. The multicultural orientation (MCO) framework, which has been linked to improved therapeutic processes and outcomes, may be a valuable tool for working with SGM clients. The primary aim of this systematic review was to link the MCO framework to existing empirical psychotherapy research with SGM clients. A secondary aim was to examine how MCO constructs that we identified within the SGM literature have been associated with therapeutic processes and outcomes with SGM clients. A systematic search of five databases yielded 61 studies that were included in the review. Framework analysis was used to extract data and identify themes and subthemes related to MCO constructs from included studies. Results of the review demonstrate how the MCO framework can be used to conceptualize psychotherapy with SGM clients and-using the MCO framework-highlight potential beneficial and harmful therapist qualities and actions when working with SGM clients. Implications for future research and psychotherapy practice with SGM clients are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

We examined the life histories of older lesbian, bisexual, and queer women, focusing on the stories they told about their bodies and sexuality from early to later life. Guided by a narrative constructionist approach, a series of two life history interviews were conducted with 17 lesbian, bisexual, and queer women aged 65-86. Two themes were constructed through a narrative thematic analysis: Queering the Corset: Negotiating Gender Expression and (Aspirational) Aging Body Acceptance. Participants experienced body-related freedom through 'tomboy' expressions of physicality as children. This body autonomy was constrained in adolescence and adulthood due to heterosexist messages surrounding idealized femininity relayed by family and (heterosexual) men, which disrupted self-care yet catalyzed attuned, queer desire and positive embodiment. Women worked to accept their bodies as they aged; they experienced some body dissatisfaction in relation to age-related body changes, yet gratitude and pride in their older queer identities. The findings highlight concurrent positive and negative body image, and breadth of body-related experiences ranging from attunement and agency to discomfort and disruption throughout the life course. This work contributes to body image and embodiment research by moving beyond dominant (youthful) heteronormative perspectives by illuminating how ageism and heterosexism can shape body-related experiences.

RESUMO

BACKGROUND: Longer-term symptoms (long COVID) may be present in seemingly recovered patients for several months and can be debilitating. AIM: To investigate the prevalence and type of symptoms in those with a prior COVID-19 diagnosis. METHODS: This prospective, longitudinal observational study commenced in July 2020 investigating the longer-term health impacts of COVID-19. Participants were recruited via public health units and media publicity. Surveys were completed upon enrolment, and at 1, 3, 6 and 12 months. Outcome measures included incidence of activity limitations and symptoms against health and vaccination status, age and gender. RESULTS: Overall, 339 participants were recruited. At 3 months after COVID-19, 66.8% reported symptoms, and 44.8% were still experiencing symptoms at 12 months. Fatigue was most common at every point (between 53.1% and 33.1%). Pain symptoms increased in relative prevalence over time, whereas respiratory/pulmonary-type symptoms decreased substantially after 3 months. Females and younger people were more likely to experience symptoms in the early stages of long COVID (P < 0.01) and those with more comorbidities in the latter stages (P < 0.001). Vaccination showed a statistically significant protective effect against symptoms (P < 0.01-0.001). CONCLUSION: Long-term COVID-19 symptoms exist among recovered patients up to 12 months after contracting the virus. Fatigue is a primary contributor, while chronic pain became more problematic after 6 months. Vaccination was a factor in preventing long-term symptoms and aiding faster recovery from symptoms. Further work exploring additional contributors to symptom prevalence would assist in developing appropriate follow-up care.

RESUMO

Introduction: Postural threat elicits modifications to standing balance. However, the underlying neural mechanism(s) responsible remain unclear. Shifts in attention focus including directing more attention to balance when threatened may contribute to the balance changes. Sample entropy, a measure of postural sway regularity with lower values reflecting less automatic and more conscious control of balance, may support attention to balance as a mechanism to explain threat-induced balance changes. The main objectives were to investigate the effects of postural threat on sample entropy, and the relationships between threat-induced changes in physiological arousal, perceived anxiety, attention focus, sample entropy, and traditional balance measures. A secondary objective was to explore if biological sex influenced these relationships. Methods: Healthy young adults (63 females, 42 males) stood quietly on a force plate without (No Threat) and with (Threat) the expectation of receiving a postural perturbation (i.e., forward/backward support surface translation). Mean electrodermal activity and anterior-posterior centre of pressure (COP) sample entropy, mean position, root mean square, mean power frequency, and power within low (0-0.05 Hz), medium (0.5-1.8 Hz), and high-frequency (1.8-5 Hz) components were calculated for each trial. Perceived anxiety and attention focus to balance, task objectives, threat-related stimuli, self-regulatory strategies, and task-irrelevant information were rated after each trial. Results and Discussion: Significant threat effects were observed for all measures, except low-frequency sway. Participants were more physiologically aroused, more anxious, and directed more attention to balance, task objectives, threat-related stimuli, and self-regulatory strategies, and less to task-irrelevant information in the Threat compared to No Threat condition. Participants also increased sample entropy, leaned further forward, and increased the amplitude and frequency of COP displacements, including medium and high-frequency sway, when threatened. Males and females responded in the same way when threatened, except males had significantly larger threat-induced increases in attention to balance and high-frequency sway. A combination of sex and threat-induced changes in physiological arousal, perceived anxiety, and attention focus accounted for threat-induced changes in specific traditional balance measures, but not sample entropy. Increased sample entropy when threatened may reflect a shift to more automatic control. Directing more conscious control to balance when threatened may act to constrain these threat-induced automatic changes to balance.

RESUMO

Shape optimization is an indispensable step in any aerodynamic design. However, the inherent complexity and non-linearity associated with fluid mechanics as well as the high-dimensional design space intrinsic to such problems make airfoil shape optimization a challenging task. Current approaches relying on gradient-based or gradient-free optimizers are data-inefficient in that they do not leverage accumulated knowledge, and are computationally expensive when integrating Computational Fluid Dynamics (CFD) simulation tools. Supervised learning approaches have addressed these limitations but are constrained by user-provided data. Reinforcement learning (RL) provides a data-driven approach bearing generative capabilities. We formulate the airfoil design as a Markov decision process (MDP) and investigate a Deep Reinforcement Learning (DRL) approach to airfoil shape optimization. A custom RL environment is developed allowing the agent to successively modify the shape of an initially provided 2D airfoil and to observe the associated changes in aerodynamic metrics such as lift-to-drag (L/D), lift coefficient (Cl) and drag coefficient (Cd). The learning abilities of the DRL agent are demonstrated through various experiments in which the agent's objective-maximizing L/D, maximizing Cl or minimizing Cd-as well as the initial airfoil shape are varied. Results show that the DRL agent is able to generate high performing airfoils within a limited number of learning iterations. The strong resemblance between the artificially produced shapes and those found in the literature highlights the rationality of the decision-making policy learned by the agent. Overall, the presented approach demonstrates the relevance of DRL to airfoil shape optimization and brings forward a successful application of DRL to a physics-based aerodynamics problem.

RESUMO

BACKGROUND: Accessory atrioventricular pathways (APs) are the most common tachycardia substrate for supraventricular tachycardia (SVT) in the young. Endocardial catheter ablation of AP may be unsuccessful in up to 5% of patients because of a coronary sinus location. OBJECTIVE: The purpose of this study was to obtain data on ablation of accessory pathways within the coronary venous system (CVS) in the young. METHODS: Analysis of feasibility, outcome, and safety in patients ≤18 years with coronary sinus accessory pathways (CS-APs) and catheter ablation via CVS in a tertiary pediatric electrophysiological referral center (May 2003 to December 2021) was performed. The control group adjusted for age, weight, and pathway location was established from patients of the prospective European Multicenter Pediatric Ablation Registry who all had undergone endocardial AP ablation. RESULTS: Twenty-four individuals underwent mapping and intended AP ablation within the CVS (age 2.7-17.3 years; body weight 15.0-72.0 kg). Because of proximity to the coronary artery, ablation was withheld in 2 of the patients. Overall procedural success was achieved in 20 of 22 study patients (90.9%) and in 46 of 48 controls (95.8%). Coronary artery injury after radiofrequency ablation was noted in 2 of 22 study patients (9%) and in 1 of 48 controls (2%). In CVS patients, repeat SVT occurred in 5 of 22 patients (23%) during median follow-up of 8.5 years, and 4 of the 5 underwent reablation, resulting in 94.4% overall success. Controls were free from SVT during follow-up of 12 months as defined by the registry protocol. CONCLUSION: Success of CS-AP ablation in the young was comparable to that of endocardial AP ablation. Substantial risk of coronary artery injury should be considered when CS-AP ablation is performed in the young.

RESUMO

The incidence of head and neck cutaneous squamous cell carcinoma (HNcSCC) is unevenly distributed between men and women. At present, the mechanism behind this disparity remains elusive. This study conducted a systematic review and meta-analysis of proportions to investigate the disparity between sexes for patients with HNcSCC. PubMed, Scopus, EMBASE, MEDLINE, Emcare and CINAHL were searched in November 2021 and June 2022 (N > 50, English, human), and studies which examined the association between sex and HNcSCC were included. Analysis was conducted using RStudio with data and forest plots displaying males as a proportion of total patients with HNcSCC. Two independent researchers performed study selection, data extraction, data analysis and risk of bias. Eighty-two studies (1948 to 2018) comprising approximately 186,000 participants (67% male, 33% female) from 29 countries were included. Significantly more males had HNcSCC overall (71%; CI: 67−74). Males were also significantly more affected by cSCC of the ear (92%; CI: 89−94), lip (74%; CI: 66−81), and eyelid (56%; CI: 51−62). This study found HNcSCC disproportionately affected males overall and across all subtypes. Improving our understanding of sex-specific mechanisms in HNcSCC will better inform our preventive, therapeutic and prognostic practices.

RESUMO

Background: Many non-binary individuals AFAB (assigned female at birth) seek gestational parenthood. However, the limited available literature is often focused on trans men and overlooks the conception, pregnancy, and birth experiences of non-binary parents. Aims: The study aimed to capture the unique reproduction narratives of non-binary people AFAB. Methods: Five non-binary individuals volunteered to participate in this study. Data were collected using largely unstructured, in-depth, tape-recorded interviews. Thematic analysis of the verbatim transcripts and tape recordings yielded a chronological, cohesive narrative for each participant. Four participants reviewed their narrative and confirmed that their story was accurately represented. The individual narratives were then woven into one collective narrative, and common themes across the participants' stories were identified. Results: Before conception, most participants considered how to balance their medical and social transitions with their reproductive goals. Conception was relatively easy and straightforward for the four participants who used their partner's sperm. The gendered nature of, and language surrounding, pregnancy greatly impacted participant's reproductive experiences, leading to feelings of isolation and loneliness, difficulties finding maternity clothes and gender dysphoria. Participants desired gender-affirming care and reported mostly positive experiences with their healthcare providers. Their gender identity influenced their experiences of parenthood, as well as the decisions they made regarding the disclosure of their gender identity to others, their gender presentation, chestfeeding, and parental designations. Discussion: The cisnormative and heteronormative scripts that surround pregnancy shaped the reproductive narratives of those who participated in this research. The findings reinforce the importance of inclusive, gender-affirming healthcare and social support services.

RESUMO

INTRODUCTION: Ovarian cancer impacts approximately 1 in 75 women. Sexual health is receiving increasing attention as a critical aspect of gynecologic cancer treatment and a component of quality of life. Therefore, investigating how women with ovarian cancer experience and express sexuality is an important area of inquiry. AIMS: To evaluate how women with ovarian cancer experience and express sexuality, a major determinant of quality of life, in the context of their illness. METHODS: In a mixed-methods approach, 6 validated self-report questionnaires (n = 64) and an in-depth focus group (n = 3) were used to gather data. RESULTS: The quantitative phase of the study showed that women with ovarian cancer have a poorer quality of life and higher rates of sexual dysfunction and sexual distress compared with published norms from the general population. They also have lower levels of relationship satisfaction and increased rates of depression. The qualitative phase of the study revealed 6 themes: (i) changes to relationship satisfaction; (ii) sexual difficulties; (iii) challenges with body image; (iv) gaps in communication with healthcare providers; (v) feelings of guilt, grief, resentment, anxiety, and fear; and (vi) strategies used for coping. CONCLUSIONS: Ovarian cancer impacts women's lives beyond mere survival, including their sexual function and quality of life. Healthcare providers are urged to prepare women with ovarian cancer for these challenges and offer information and resources to help improve their quality of life and sexuality.
