RESUMO

Assertive Community Treatment (ACT) model is the gold standard in community psychiatry serving people with severe mental illness. With its outreach-based design, the pandemic has profoundly affected the operations and functioning of ACT. The Dartmouth ACT Scale (DACTS) provides a standardized comprehensive and quantitative way to evaluate ACT quality. Results could inform nature of impact and identify areas for improvement. Current online survey used DACTS during the pandemic in April-May 2021. Clinical and administrative leadership of the 80 ACT teams in Ontario, Canada cross-sectionally rated ACT quality one-year pre-Covid (2018-2019) and one-year post the start of Covid (2020-2021). The overall pre-Covid Ontario ACT DACTS fidelity was 3.65. The pandemic led to decreases in all domains of DACTS (Human Resources: -4.92%, p < 0.001, 95% CI [0.08-0.27]; Organizational Boundary: -1.03%, p < 0.013,95%CI [0.01-0.07]; and Nature of Services: -6.18%, p < 0.001, 95%CI [0.16-0.26]). These changes were accounted by expected lower face-to-face encounters, time spent with clients, reduction in psychosocial services, less interactions with hospitals and diminished workforces. The magnitude of change was modest (-3.84%, p < 0.001, 95%CI [0.09-0.19]). However, the Ontario ACT pre-Covid DACTS was substantially lower (-13.5%) when compared to that from a similar survey 15 years ago (4.22), suggestive of insidious systemic level loss of fidelity. Quantitative fidelity evaluation helped to ascertain specific pandemic impact. Changes were significant and specific, but overall relatively modest when compared to the larger system level drop over the last decade. There is both evidence for model adaptability and resilience during Covid disruption, and concerns over larger downward drift in ACT fidelity and quality.

RESUMO

This exploratory qualitative study examines holy water priest healers' explanatory models and general treatment approaches toward mental illness, and their views and reflections on a collaborative project between them and biomedical practitioners. The study took place at two holy water treatment sites in Addis Ababa, Ethiopia. Twelve semi-structured interviews with holy water priest healers found eight notable themes: they held multiple explanatory models of illness, dominated by religious and spiritual understanding; they emphasized spiritual healing and empathic understanding in treatment, and also embraced biomedicine as part of an eclectic healing model; they perceived biomedical practitioners' humility and respect as key to their positive views on the collaboration; they valued recognition of their current role and contribution in providing mental healthcare; they recognized and appreciated the biomedical clinic's effectiveness in treating violent and aggressive patients; they endorsed the collaboration and helped to overcome patient and family reluctance to the use of biomedicine; they lamented the lack of spiritual healing in biomedical treatment; and they had a number of dissatisfactions and concerns, particularly the one-way referral from religious healers to the biomedical clinic. The study results show diversity in the religious healers' etiological understanding, treatment approaches and generally positive attitude and views on the collaboration. We present insights and explorations of factors affecting this rare, but much needed collaboration between traditional healers and biomedical services, and potential ways to improve it are discussed.

RESUMO

OBJECTIVE: In Canada and elsewhere, making treatment decisions for a person with serious mental illness (SMI) who was found incapable for treatment decisions via a substitute decision maker (SDM) is the norm. This practice is often called into question from a rights-based perspective. The literature on the views of affected individuals is limited. We explore the experiences of adults with SMI who have had SDMs to gain more in-depth understanding. METHOD: We conducted semistructured interviews with 11 consumers of psychiatric services who have had experiences with SDM (range 1-12 years) at an urban hospital in Toronto, Canada. RESULTS: Thematic analysis showed five main themes and related subthemes, including: (1) strong dissatisfaction with and rejection of the SDM's role and purpose; (2) pervasive sense of stigma associated with having a SDM; (3) ongoing struggles to gain autonomy; (4) mixed changes in relationship with and views about SDM; and (5) views on how to improve SDM process. CONCLUSION AND IMPLICATIONS FOR PRACTICE: Our study highlights substantial dissatisfaction with the current SDM system and approaches among adults with SMI who have had SDMs. Issues of stigma and struggles to regain autonomy are prevalent. We discuss the personal, clinical, and social-legal contexts in which they occur, particularly in light of the United Nations' Convention on the Rights of Persons with Disabilities that calls for replacing SDMs with supported decision making. Rights-based approaches to care carry substantial practice implications and call for thoughtful change management. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

BACKGROUND: Understanding the neural mechanism underlying the transition from suicidal ideation to action is crucial but remains unclear. To explore this mechanism, we combined resting-state functional connectivity (rsFC) and computational modeling to investigate differences between those who attempted suicide(SA) and those who hold only high levels of suicidal ideation(HSI). METHODS: A total of 120 MDD patients were categorized into SA group (n=47) and HSI group (n=73). All participants completed a resting-state functional MRI scan, with three subregions of the insula and the dorsal anterior cingulate cortex (dACC) being chosen as the region of interest (ROI) in seed-to-voxel analyses. Additionally, 86 participants completed the balloon analogue risk task (BART), and a five-parameter Bayesian modeling of BART was estimated. RESULTS: In the SA group, the FC between the ventral anterior insula (vAI) and the superior/middle frontal gyrus (vAI-SFG, vAI-MFG), as well as the FC between posterior insula (pI) and MFG (pI-MFG), were lower than those in HSI group. The correlation analysis showed a negative correlation between the FC of vAI-SFG and psychological pain avoidance in SA group, whereas a positive correlation in HSI group. Furthermore, the FC of vAI-MFG displayed a negative correlation with loss aversion in SA group, while a positive correlation was found with psychological pain avoidance in HSI group. CONCLUSION: In current study, two distinct neural mechanisms were identified in the insula which involving in the progression from suicidal ideation to action. Dysfunction in vAI FCs may gradually stabilize as individuals experience heightened psychological pain, and a shift from positive to negative correlation patterns of vAI-MFC may indicate a transition from state to trait impairment. Additionally, the dysfunction in PI FC may lead to a lowered threshold for suicide by blunting the perception of physical harm.

RESUMO

Using an online survey distributed to members of the provincial organization that represents the 88 Assertive Community Treatment (ACT) and Flexible ACT teams in Ontario, Canada, this descriptive study relied on the unique vantage points and observations of the front-line community psychiatry workers who maintained contact with patients through outreach and telecommunication during the height of COVID-19. The patients who suffer from serious mental illness (SMI) were uniquely affected by COVID-19 due to the changes, reduction or shut down of many essential clinical and community support services. Thematic and quantitative analyses of the workers' observations highlighted 6 main areas of note, including significant social isolation and loneliness, clinical course deterioration and life disruption, increased hospital and ER use, police and legal contacts, and substance abuse and related deaths. There were also encouraging signs of positive adaptations in terms of independence and resilience. Reflections of these impacts and potential ameliorating approaches are further discussed.

RESUMO

Across jurisdictions, the use of 'leverage' to promote adherence to mental health treatment is widespread. However, little research exists on the possible association between the application of leverage and personal recovery. We examined the prevalence of various forms of leverage in a Canadian context and compared these rates with those in other jurisdictions. Additionally, we examined the relationship between two prominent forms of leverage (financial and housing) and the experience of personal recovery. Structured interviews were conducted with people receiving community-based mental health care in Toronto, Canada. Rates of overall leverage in our sample were similar to rates reported in other jurisdictions. Personal recovery was negatively associated with financial leverage but was not associated with housing leverage. Our results highlight the importance of separately examining the relationship of specific forms of leverage and personal recovery and raise questions for future research about the possible effect of financial leverage on recovery.

RESUMO

In the era of on-going efforts to empower persons with mental illness to be independent decision makers as informed by the United Nations' Convention on the Rights of Persons with Disability (CRPD), family members acting as substitute decision makers (SDM) for people suffering from disabling serious mental illness (SMI) remain an integral part of the medical-legal system in psychiatric care in many parts of the world, including Canada; yet their experiences and perspectives are rarely studied. This explorative qualitative study examines the lived experiences and reflections of 14 family member SDMs in Toronto, Canada. Five key themes related to being SDM emerged: 1) Varied subjective understanding of the responsibility and authority of the SDM role; 2) Varied role demands and impact on SDMs' lives; 3) Challenges in dealing with the mental health system; 4) Leveraging decision making status to promote patient care; and 5) SDM role impact on family relationships. The need to improve SDM understanding of their role, acknowledging their value and care-taker burden, finding a balance for their involvement, and improving their support in efforts to enhance care for the patients are discussed.

RESUMO

Assessment of a patient's capacity to make treatment decisions and working with the wishes of a patient with mental illness against the best medically indicated plan is a complex and dynamic task. It is particularly challenging when the course of deterioration of the illness is meandering and slow, and the time horizon for recovery is uncertain, providing no clear point of entry for definitive crisis intervention. High-impact decisions concerning body integrity, such as the amputation of a leg, further complicate the task. To highlight these challenges and complexities, we present the case of a man who suffered from schizophrenia, with a worsening diabetic foot ulcer and suboptimal acceptance of proper wound care. The patient died as a result of his refusal of a proposed amputation to address his life-threatening infection. Medical system and cultural issues are also considered.

RESUMO

BACKGROUND: In the last decade, suicidality has been increasingly theorized as a distinct phenomenon from major depressive disorder (MDD), with unique psychological and neural mechanisms, rather than being mostly a severe symptom of MDD. Although decision-making biases have been widely reported in suicide attempters with MDD, little is known regarding what components of these biases can be distinguished from depressiveness itself. METHODS: Ninety-three patients with current MDD (40 with suicide attempts [SA group] and 53 without suicide attempts [NS group]) and 65 healthy controls (HCs) completed psychometric assessments and the balloon analog risk task (BART). To analyze and compare decision-making components among the three groups, we applied a five-parameter Bayesian computational modeling. RESULTS: Psychological assessments showed that the SA group had greater suicidal ideation and psychological pain avoidance than the NS group. Computational modeling showed that both MDD groups had higher risk preference and lower ability to learn and adapt from within-task observations than HCs, without differences between the SA and NS patient groups. The SA group also had higher loss aversion than the NS and HC groups, which had similar loss aversion. CONCLUSIONS: Our BART and computational modeling findings suggest that psychological pain avoidance and loss aversion may be important suicide risk factor that are distinguishable from depression illness itself.

RESUMO

Objective: Psychiatric interventions that consider the socio-cultural and spiritual traditions of patients are needed to address stigma and improve access to mental health services. Productive collaboration between traditional healers and biomedical practitioners hold promise in such efforts, and applying tenets of transformative learning hold potential for mitigating an overemphasis on biomedical models in such collaboration. We present a framework for how to engage in health system reform to enhance mental health services in communities that are distrustful of, or unfamiliar with biomedical approaches. Our research question was how to bridge two seemingly opposing paradigms of mental health care, and we sought to understand how the theory of transformational learning (TLT) can be applied to learning among Religious healers and biomedical practitioners in culturally appropriate ways to improve collaboration. Methods: TLT informed the development, implementation, and evaluation of an educational intervention in Addis Ababa, Ethiopia that aimed to improve delivery of mental health services at two Holy water sites. The initiative involved both psychiatrists and religious healers with extensive experience providing care to mentally ill patients. Using a focused ethnographic approach that incorporates document analysis methodology, this qualitative study examined recordings and minutes of stakeholder meetings, workshops and informal interviews with participants, analyzed for evidence of Mezirow's 11 stages of transformative learning. A participatory action approach was used to encourage practice change. Results: All participants exhibited a high degree of engagement with the of the collaborative project and described experiencing "disorienting dilemmas" by Mezirow's classic description. Opportunities to reflect separately and in large groups encouraged a re-examination of attitudes previously contributing to siloed approaches to care and led to instrumental changes in mental health care delivery and a higher degree of coordination and collaboration between psychiatrists and traditional healers. Conclusion: Our study demonstrates the utility of TLT in both the design and evaluation of initiatives aiming to bridge cross-cultural and cross-professional divides. The learning process was further enhanced by a collaborative participatory action model adjusted to accommodate Ethiopian socio-political and cultural relations.

RESUMO

BACKGROUND: Psychomotor retardation (PMR) is frequently noted as a characteristic feature of major depressive disorder (MDD). In patients with depression, it is characterized by retardation of speech, emotion, thinking, and cognition. This study explored the activation pattern of the prefrontal cortex (PFC) during the finger-tapping task (FTT) in subjects with MDD, aiming to provide additional understanding on the connection between PMR and PFC activation pattern in depression through the use of near-Infrared Spectroscopy (NIRS). We hypothesized that, through use of NIRS during the FTT, motor retardation in depression would generate a distinct PFC activation pattern, allowing for differentiation between patients with MDD and healthy controls (HCs). METHODS: Thirty-five patients with MDD and thirty-nine HCs underwent NIRS evaluation during performance of the FTT. The FTT included both left-finger tapping and right-finger tapping performed by a computer screen. Each participant was assessed using a 45-channel NIRS and various clinical scales. FINDINGS: During the left-FTT, the left orbitofrontal cortex (OFC) showed higher oxy-hemoglobin (Oxy-Hb) activation in the MDD group when compared to the HCs. During the right-FTT, the right dorsolateral prefrontal cortex (DLPFC) demonstrated lower Oxy-Hb activation, and the dorsomedial prefrontal cortex (DMPFC) showed higher Oxy-Hb activation in the MDD group versus the HC group. CONCLUSION: Our results demonstrated different activation patterns of the PFC between the MDD and HC groups, using FTT as a motor performance task. In particular, the OFC, the DLPFC and the DMPFC areas hold promise as new useful sites for such differentiation in future investigations.

RESUMO

Recognizing futility is a challenging aspect of clinical medicine, particularly in psychiatry. We present a case of a man who suffered from clozapine-resistant schizophrenia. His illness was characterized by prominent religious delusions and severe self-starvation. Neither the intensity of his symptoms nor his quality of life improved with available psychiatric interventions, and he experienced significant iatrogenic harms from enforced treatments. Recognizing clinical futility, in collaboration with a diverse multidisciplinary team, and making a clear shift to a patient-centered palliative approach allowed the patient's treatment team to prioritize his autonomy and subjective meaning in his final months. Such approaches are understudied in psychiatry and warrant greater attention.

RESUMO

Wnt signaling pathways have been extensively studied in the context of several diseases, including cancer, coronary artery disease, and age-related disorders. ß-Catenin plays a central role in the most studied Wnt pathways, the Wnt/ß-catenin signaling pathway, commonly referred to as the canonical Wnt signaling pathway. ß-catenin is a substrate of glycogen synthase kinase 3ß (GSK-3ß), and the phosphorylated ß-catenin by GSK-3ß can be degraded by the proteasome through ubiquitination. Thus, GSK-3ß inhibitors have become a widely used chemical biology tool to study the canonical Wnt signaling pathway. Among the varied GSK-3ß inhibitors, a compound known as CHIR-99021 is one of the most widely used. Although these inhibitors contribute greatly to our understanding of the canonical Wnt pathway, certain pitfalls associated with such an approach may have been overlooked. In many published studies, micromolar concentrations of CHIR-99021 are used to activate the canonical Wnt pathway. Although CHIR-99021 is a specific GSK-3ß inhibitor, it specifically inhibits the kinase at the nanomolar level. Therefore, caution is required when micromolar levels of CHIR-99021 are used for the purpose of activating the canonical Wnt signaling pathway.

RESUMO

Filial piety involves the Confucian view that children always have a duty to be obedient and to provide care for their parents. Filial piety has been described as both a risk and a protective factor in depression and suicide. This qualitative study aimed to explore the role of filial piety in the suicidal behavior of Chinese women. Qualitative interviews were conducted with Chinese women with a history of suicidal behavior living in the Beijing area (n = 29). Filial piety data were extracted and analyzed in accordance with constructivist grounded theory. The women described five specific family and filial piety factors and how they influenced their ability to fulfill family role obligations, which was described as a nexus connecting these factors to depression, suicidal behavior, and recovery. The five factors were: 1) rigidity of parental filial expectations, 2) perception of family relationships as positive/supportive or negative/harsh, 3) whether filial piety is of high or low personal value in the woman's life, 4) any experiences of rebellion leading to punitive consequences, and 5) how much filial piety she receives from her children. These factors could inform suicide risk assessments in this population. They can be harnessed as part of recovery and protect against future suicidal behavior.

RESUMO

Drawing on ethnographic data collected in three informal communities, one in Argentina, one in México, and one in Ecuador, we address the long-standing question posed by Larissa Lomnitz's and Carol Stack's now-classic studies of how impoverished people not only survive but what strategies they adopt in an attempt to build a dignified life. By focusing on the diversity of strategies by which the urban poor solve the everyday problems of individual and collective reproduction, we move beyond the macro-level analysis of structural constraint and material deprivation. Our findings show a remarkable continuity in the difficulties residents of these informal communities confronted and the problem-solving strategies they resorted to. We found that networks of kin and friends continue to play a crucial role in how poor people not only survive but attempt to get ahead. Additionally, we highlight the role of patronage networks and collective action as central to strategies by which the urban poor cope with scarcity and improve their life chances, while also paying close attention to ways in which they deal with pressing issues of insecurity and violence. The paper shows that poor people's survival strategies are deeply imbricated in routine political processes.

RESUMO

OBJECTIVE: Predicting suicide is notoriously difficult and complex, but a serious public health issue. An innovative approach utilizing machine learning (ML) that incorporates features of psychological mechanisms and decision-making characteristics related to suicidality could create an improved model for identifying suicide risk in patients with major depressive disorder (MDD). METHOD: Forty-four patients with MDD and past suicide attempts (MDD_SA, N = 44); 48 patients with MDD but without past suicide attempts (MDD_NS, N = 48-42 of whom with suicide ideation [MDD_SI, N = 42]), and healthy controls (HCs, N = 51) completed seven psychometric assessments including the Three-dimensional Psychological Pain Scale (TDPPS), and one behavioral assessment, the Balloon Analogue Risk Task (BART). Descriptive statistics, group comparisons, logistic regressions, and ML were used to explore and compare the groups and generate predictors of suicidal acts. RESULTS: MDD_SA and MDD_NS differed in TDPPS total score, pain arousal and avoidance subscale scores, suicidal ideation scores, and relevant decision-making indicators in BART. Logistic regression tests linked suicide attempts to psychological pain avoidance and a risk decision-making indicator. The resultant key ML model distinguished MDD_SA/MDD_NS with 88.2% accuracy. The model could also distinguish MDD_SA/MDD_SI with 81.25% accuracy. The ML model using hopelessness could classify MDD_SI/HC with 94.4% accuracy. CONCLUSION: ML analyses showed that motivation to avoid intolerable psychological pain, coupled with impaired decision-making bias toward under-valuing life's worth are highly predictive of suicide attempts. Analyses also demonstrated that suicidal ideation and attempts differed in potential mechanisms, as suicidal ideation was more related to hopelessness. ML algorithms show useful promises as a predictive instrument.
