RESUMO

BACKGROUND: Sexual violence has a several negative impact on women's health. Thus, the health system is a gateway for the multisector response to victims. In 2018, the Clinical Forensic Hospital Units (UCFH) in Chile were launched for this purpose. OBJECTIVE: To evaluate the state of implementation of the UCFH in the health services (HS) in Chile. METHOD: This is a quantitative descriptive, cross-sectional study. A survey was designed and applied through the Google Forms platform to the managers of the care and prevention network for victims of sexual violence (VSV) of each SS. The contact of each manager was requested by each HS in three ways: transparency law, lobby law, and telephone. Each HS was classified according to the existence or not of UCFH and for each unit the availability of resources was evaluated according to the recommendations of the Technical Standard of Attention to VSV of the Ministry of Health. Also, the functioning of each unit during the pandemic was evaluated. RESULTS: Twenty-four of the 29 HSs responded, of which 12 reported having UCFH. Of the 12 units, 50% had complete infrastructure, 58.3% had complete instruments, none had full human resources, 50% had partial HR, 50% had sampling complete, and 58. 3% had full health benefits. The function during the pandemic was affected in 25% of the units. CONCLUSION: Challenges persist in the implementation of the UCFH, with special limitations in the availability of human resources.

RESUMO

ATP citrate lyase (ACLY) inhibitors have the potential of modulating central processes in protein, carbohydrate, and lipid metabolism, which can have relevant physiological consequences in aging and age-related diseases. Here, we show that hepatic phospho-active ACLY correlates with overweight and Model for End-stage Liver Disease score in humans. Wild-type mice treated chronically with the ACLY inhibitor potassium hydroxycitrate exhibited delayed early mortality. In AML12 hepatocyte cultures, the ACLY inhibitors potassium hydroxycitrate, SB-204990, and bempedoic acid fostered lipid accumulation, which was also observed in the liver of healthy-fed mice treated with potassium hydroxycitrate. Analysis of soleus tissue indicated that potassium hydroxycitrate produced the modulation of wound healing processes. In vivo, potassium hydroxycitrate modulated locomotor function toward increased wire hang performance and reduced rotarod performance in healthy-fed mice, and improved locomotion in mice exposed to cardiotoxin-induced muscle atrophy. Our findings implicate ACLY and ACLY inhibitors in different aspects of aging and muscle regeneration.

RESUMO

Although Native (American Indian and Alaska Native [AI/AN]) populations have high rates of abstinence from alcohol, health problems associated with substance use remain a pressing concern in many AI/AN communities. As part of a longstanding community-based participatory research (CBPR) project involving five years of relationship building and three preliminary studies, our team of academic and community co-researchers developed a culturally grounded intervention to facilitate recovery from substance use disorders among tribal members from a rural AI reservation. Our Indigenous Recovery Planning (IRP) intervention consists of six weekly sessions and aims to provide inroads to existing resources in the community, affirm and enhance Native identity, address culturally relevant risk factors, and build upon strengths. Results from a feasibility pilot study (N = 15) suggest that IRP is feasible to implement and acceptable to the community. Although there was insufficient statistical power to conduct hypothesis testing, there were changes between pretest and posttest scores in the expected directions. Future directions and limitations of this research are discussed.

RESUMO

INTRODUCTION: The concealment of suicidal ideation (SI) constitutes a significant barrier to reducing veteran deaths by suicide and is associated with fear of negative consequences (e.g., involuntary hospitalization). This study examined whether augmenting informed consent with psychoeducation aimed to help patients achieve a more realistic risk appraisal of consequences associated with disclosure of SI, decreased hesitancy to disclose SI, and related risk behaviors among U.S. veterans. METHOD: Participants (N = 133) were recruited from combat veteran social media groups and were randomly assigned to a video simulated treatment-as-usual informed consent (control) or to one of two psychoeducation-enhanced informed consent conditions (psychoed, psychoed + trust). RESULTS: Compared with the control group, participants in both psychoeducation and enhanced informed consent conditions reported lower hesitancy to disclose SI, firearm access, and problems with drugs/thoughts of harming others, as well as greater trust and respect for the simulated clinician. CONCLUSIONS: These findings suggest that brief psychoeducation regarding common factors that affect hesitancy to disclose SI may be beneficial for increasing trust in providers during the informed consent process and decreasing concealment of SI and firearm access among veterans.

RESUMO

Oligodendrocyte precursor markers have become of great interest to identify new diagnostic and therapeutic targets for diffuse gliomas, since state-of-the-art studies point towards immature oligodendrocytes as a possible source of gliomagenesis. Brain enriched myelin associated protein 1 (BCAS1) is a novel marker of immature oligodendrocytes and was proposed to contribute to tumorigenesis in non-central nervous system tumors. However, BCAS1 role in diffuse glioma is still underexplored. This study analyzes the expression of BCAS1 in different tumor samples from patients with diffuse gliomas (17 oligodendrogliomas; 8 astrocytomas; 60 glioblastomas) and uncovers the molecular and ultrastructural features of BCAS1+ cells by immunostaining and electron microscopy. Our results show that BCAS1+ cells exhibit stellate or spherical morphology with similar ultrastructural features. Stellate and spherical cells were detected as isolated cells in all studied gliomas. Nevertheless, only stellate cells were found to be proliferative and formed tightly packed nodules with a highly proliferative rate in oligodendrogliomas. Our findings provide a comprehensive characterization of the BCAS1+ cell population within diffuse gliomas. The observed proliferative capacity and distribution of BCAS1+ stellate cells, particularly in oligodendrogliomas, highlight BCAS1 as an interesting marker, warranting further investigation into its role in tumor malignancy.

RESUMO

For American Indians and Alaska Native (AIAN) and other communities of color, experiences with discrimination and historical trauma may contribute to healthcare system distrust and negatively affect health care decisions, including vaccination. A saturated path analysis was conducted to examine the direct and indirect associations of thoughts regarding historical losses (of culture, language, and traditional ways) and AIAN racial discrimination with historical loss associated distress, healthcare system distrust, and COVID-19 vaccine hesitancy among AIAN college students (N = 391). Historical loss thoughts and experiences with racial discrimination were strongly associated with each other, and both were uniquely associated with greater historical loss associated distress. In turn, historical loss associated distress was associated with greater healthcare system distrust, which in turn was associated with greater likelihood of being COVID-19 vaccine hesitant. While further research is needed, the findings suggest that to address health disparities for AIAN people it is necessary to consider how to best overcome healthcare system distrust and factors that contribute to it, including historical trauma and contemporary experiences with discrimination.

RESUMO

Amyotrophic lateral sclerosis (ALS) is a fatal and incurable neurodegenerative disease affecting motor neurons and characterized by microglia-mediated neurotoxic inflammation whose underlying mechanisms remain incompletely understood. In this work, we reveal that MAPK/MAK/MRK overlapping kinase (MOK), with an unknown physiological substrate, displays an immune function by controlling inflammatory and type-I interferon (IFN) responses in microglia which are detrimental to primary motor neurons. Moreover, we uncover the epigenetic reader bromodomain-containing protein 4 (Brd4) as an effector protein regulated by MOK, by promoting Ser492-phospho-Brd4 levels. We further demonstrate that MOK regulates Brd4 functions by supporting its binding to cytokine gene promoters, therefore enabling innate immune responses. Remarkably, we show that MOK levels are increased in the ALS spinal cord, particularly in microglial cells, and that administration of a chemical MOK inhibitor to ALS model mice can modulate Ser492-phospho-Brd4 levels, suppress microglial activation, and modify the disease course, indicating a pathophysiological role of MOK kinase in ALS and neuroinflammation.

RESUMO

OBJECTIVES: Belief in an American Indian/Alaska Native (AIAN) specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIANs. Despite a notable lack of evidence that biogenetic factors play a greater role in the development of alcohol problems among AIANs than other groups, many people still believe this myth. Consistent with theory and evidence that greater experiences with discrimination leads to the internalization of stereotypes and oppression, we hypothesized that greater perceived racial discrimination (racism) would be associated with greater BV belief, but that having a stronger ethnic identity would weaken this association. We also examined whether previous substance use treatment as well as participation in Alcoholics Anonymous (AA) or Narcotics Anonymous (NA) was associated with BV belief. METHOD: Participants were 198 reservation-dwelling AI adults with a substance use problem who completed a survey as part of a larger community-based participatory study. RESULTS: A multiple regression analysis revealed that greater systemic racism was associated with greater belief in a BV; this association was not moderated by ethnic identity. Greater interpersonal racism was also associated with greater BV belief-but only among those low in ethnic identity. A regression analysis revealed that previous treatment, AA, and NA participation were not associated with BV belief. CONCLUSIONS: Greater systemic and interpersonal racism were associated with belief in a BV, and greater ethnic identity buffered the association between interpersonal racism and BV belief. This suggests that both combatting racism and fostering positive ethnic identity may help to lessen BV belief. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

OBJECTIVE: In the American Indian and Alaska Native (AIAN) population there is a discrepancy between high rates of mental health needs and low utilization rates of mental health services. This study sought to explore whether historical trauma and racial discrimination are associated with health care system (HCS) distrust and negative attitudes toward seeking mental health services. METHOD: Participants were AIAN college students (n = 392) who completed a cross-sectional online survey. A sequential mediation analysis examined whether historical trauma (thoughts and associated symptoms) was associated with less favorable attitudes toward seeking mental health services, and whether distrust of the HCS mediated this association. A second mediation analysis examined whether perceived racial discrimination was associated with less favorable attitudes toward seeking mental health services, and whether distrust of the HCS mediated this association. RESULTS: Greater reported historical trauma (thoughts and associated symptoms) and racial discrimination were associated with greater distrust of the HCS, which in turn was associated with less favorable attitudes toward seeking mental health services. Perceived racial discrimination was also directly associated with less favorable attitudes toward seeking mental health services. CONCLUSION: Historical trauma and perceived racial discrimination appear to contribute to less favorable attitudes toward seeking mental health services through their association with distrust of the HCS. This suggests that attempts to address the underutilization of mental health services in the AIAN population should consider the potential roles of historical trauma, racial discrimination, and distrust.

RESUMO

ATP-citrate lyase is a central integrator of cellular metabolism in the interface of protein, carbohydrate, and lipid metabolism. The physiological consequences as well as the molecular mechanisms orchestrating the response to long-term pharmacologically induced Acly inhibition are unknown. We report here that the Acly inhibitor SB-204990 improves metabolic health and physical strength in wild-type mice when fed with a high-fat diet, while in mice fed with healthy diet results in metabolic imbalance and moderated insulin resistance. By applying a multiomic approach using untargeted metabolomics, transcriptomics, and proteomics, we determined that, in vivo, SB-204990 plays a role in the regulation of molecular mechanisms associated with aging, such as energy metabolism, mitochondrial function, mTOR signaling, and folate cycle, while global alterations on histone acetylation are absent. Our findings indicate a mechanism for regulating molecular pathways of aging that prevents the development of metabolic abnormalities associated with unhealthy dieting. This strategy might be explored for devising therapeutic approaches to prevent metabolic diseases.

RESUMO

Human induced pluripotent stem cells (iPSCs) provide a virtually inexhaustible source of starting material for next generation cell therapies, offering new opportunities for regenerative medicine. Among different cell sources for the generation of iPSCs, urine cells are clinically relevant since these cells can be repeatedly obtained by non-invasive methods from patients of any age and health condition. These attributes encourage patients to participate in preclinical and clinical research. In particular, the use of urine-derived iPSC products is a convenient strategy for children with brain tumors, which are medically fragile patients. Here, we investigate the feasibility of using urine samples as a source of somatic cells to generate iPSC lines from pediatric patients with brain tumors (BT-iPSC). Urinary epithelial cells were isolated and reprogrammed using non-integrative Sendai virus vectors harboring the Yamanaka factors KLF4, OCT3/4, SOX2 and C-MYC. After reprogramming, BT-iPSC lines were subject to quality assessment and were compared to iPSCs obtained from urine samples of non-tumor pediatric patients (nonT-iPSC). We demonstrated that iPSCs can be successfully derived from a small volume of urine obtained from pediatric patients. Importantly, we showed that BT-iPSCs are equivalent to nonT-iPSCs in terms of morphology, pluripotency, and differentiation capacity into the three germ layers. In addition, both BT-iPSCs and nonT-iPSCs efficiently differentiated into functional mesenchymal stem/stromal cells (iMSC) with immunomodulatory properties. Therefore, this study provides an attractive approach to non-invasively generate personalized iMSC products intended for the treatment of children with brain tumors.

RESUMO

OBJECTIVE: Patients and physicians can naturally adopt hybrid healthcare models that combine face-to-face consultations with telemedicine. The study's objective was to compare the impact of two healthcare interventions, hybrid care modality and face-to-face consultation, on the patient-reported outcomes of rheumatoid arthritis patients, during the COVID-19 pandemic. METHODS: Consecutive outpatients reincorporated to a clinic previously in lockdown were invited to a non-inferiority, randomized study (October 2020--May 2022). Patients were randomized to 6 months of face-to-face consultation or hybrid care modality (intervention period-1) and then the converse modality (intervention period-2). The primary outcome was disease activity/severity behavior (Routine Assessment of Patient Index Data 3). Additional patient-reported outcomes were disability (Health Assessment Questionnaire Disability Index), quality-of-life (World Health Organization quality of life questionnaire-brief version), adherence and satisfaction with medical care, and treatment recommendation. Sample size calculation established 55 patients/healthcare interventions. RESULTS: There were 138 patients invited to participate, 130 agreed and 121 completed their study participation. Sixty-one and 60 patients respectively, received face-to-face consultation and hybrid care modality over intervention period-1. Patients were primarily middle-aged females (90.1%), with (median, IQR) 12 (9-16) years of education, long-standing disease, working (62.8%), receiving disease-modifying anti-rheumatic drugs (96.7%), and corticosteroids (61.2%). Patients had low disease activity (median Routine Assessment of Patient Index Data 3: 2.7) and Health Assessment Questionnaire Disability Index score that translated into the absence of disability, while quality of life was compromised. Baseline characteristics were similar between patients assigned to each healthcare intervention. Differences in Routine Assessment of Patient Index Data 3 behavior were below the non-inferiority margin. Results considered the order in which patients received the intervention and baselines scores, and extended to the patient-reported outcomes left. CONCLUSIONS: Hybrid care modality was non-inferior to in-person consultations in achieving patient-reported outcomes during the COVID-19 pandemic in rheumatoid arthritis patients.

RESUMO

Beneficial properties of mesenchymal stromal cells (MSCs) have prompted their use in preclinical and clinical research. Accumulating evidence has been provided for the therapeutic effects of MSCs in several pathologies, including neurodegenerative diseases, myocardial infarction, skin problems, liver disorders and cancer, among others. Although MSCs are found in multiple tissues, the number of MSCs is low, making in vitro expansion a required step before MSC application. However, culture-expanded MSCs exhibit notable differences in terms of cell morphology, physiology and function, which decisively contribute to MSC heterogeneity. The changes induced in MSCs during in vitro expansion may account for the variability in the results obtained in different MSC-based therapy studies, including those using MSCs as living drug delivery systems. This review dissects the different changes that occur in culture-expanded MSCs and how these modifications alter their therapeutic properties after transplantation. Furthermore, we discuss the current strategies developed to improve the beneficial effects of MSCs for successful clinical implementation, as well as potential therapeutic alternatives.

RESUMO

Introduction: The objectives of this study were to compare the quality-of-care and compliance with medical record regulations between in-person consultations (QIP and CIP) and telephone consultations (QTP and CTP), from rheumatoid arthritis (RA) outpatients, during the COVID-19 pandemic, and to explore the impact of the consultation modality on the treatment. Methods: Data from 324 medical notes corresponding to rheumatic consultations between July and December 2020 were abstracted. Notes were selected considering a stratified (in-person and telephone consultations) random sampling strategy. QIP, CIP, QTP, and CTP were scored based on prespecified criteria as percentages, where higher numbers translated into better standards. Logistic regression analysis investigated the association between the consultation modality and the treatment recommendation (dependent variable). Results: There were 208 (64.2%) medical notes related to in-person consultations and 114 (35.2%) to telephone consultations. Overall, medical notes corresponded to middle-aged women with long-standing disease. QIP was superior to QTP (median, interquartile range): 60% (60-75%) versus 50% (25-60%), p ≤ 0.001, and differences were related to disease activity and prognosis documentation (81.3% vs. 34.5% and 55.8% vs. 33.6%, respectively, p ≤ 0.001) and the prolonged prescription of glucocorticoids with a documented management plan (58.5% vs. 30.4%, p = 0.045). Meanwhile, CIP and CTP were similar. Telephone consultation was a significant risk factor for no changes in the treatment recommendation (odds ratio: 2.113, 95% confidence interval: 1.284-3.479, p = 0.003), and results were consistent in the 142 medical notes with documented absence of disease activity. Conclusions: In the clinical context of RA, the quality-of-care provided by telephone consultations is below the standard of care and impacts the treatment.

RESUMO

BACKGROUND: Belief in the myth of an American Indian/Alaska Native (AIAN)-specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIAN college students who drink, despite also being associated with greater attempts to reduce drinking. This study examined the association of belief in a BV with alcohol use among reservation-dwelling AI adults with a substance use problem. METHODS: Participants (n = 141) who drank alcohol in the past 90 days were selected from a larger AI sample who self-identified as having a substance use problem. Moderated-mediation analyses examined whether belief in a BV was positively associated with alcohol- and substance use-related consequences and whether self-efficacy and craving mediated the association of belief in a BV with alcohol use. RESULTS: Among participants who reported using alcohol but not hard drugs (e.g., methamphetamine, opioids), greater belief in a BV was associated with more drinking days, which in turn was associated with greater alcohol-related consequences. Among participants who used alcohol only, belief in a BV was also significantly associated with greater craving, and in turn with more drinking days. Among individuals who used both alcohol and hard drugs, greater belief in a BV was associated with fewer drinking days, but was not significantly associated with substance use-related consequences. No association was found between belief in a BV and self-efficacy to avoid alcohol or drug use. CONCLUSIONS: Among individuals who use only alcohol, belief in a BV may contribute to more drinking days and greater alcohol-related consequences through its association with greater craving. This study provides further evidence of the potential harm of internalizing the belief that being AIAN contributes to the risk for alcohol problems, a notion that lacks scientific evidence despite decades of research. The findings highlight the importance of combating societal myths regarding AIAN peoples and the internalization of these stereotypes.

RESUMO

OBJECTIVE: Polymyalgia rheumatica (PMR) is the most common inflammatory disease in patients over 50 years. Information about the disease in Latin America (LATAM) is scarce. We aimed to evaluate a group of Colombian patients with PMR and to conduct a systematic review of PMR in LATAM. METHODS: A multicentric retrospective study was performed. Medical records of 256 PMR patients were evaluated. Patients were divided into two groups, those fulfilling the 2012 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for PMR and those who did not (i.e., clinical diagnosis). A systematic literature review and meta regression was performed comparing Colombian vs LATAM patients. RESULTS: From 256 patients, 145 (56.6%) fulfilled the 2012 EULAR/ACR criteria, and 111 (43.3%) were classified by clinical diagnosis. Inflammatory bilateral shoulder pain, pelvic girdle aching, morning stiffness >45 min, elevated erythrocyte sedimentation rate (ESR), and C-reactive protein (CPR), and Methotrexate (MTX) prescription were more common in the 2012 EULAR/ACR group. None of the included patients presented overt polyautoimmunity (PolyA), whereas up to 24% exhibited latent PolyA. In addition, these patients showed high frequency of malignancy (7.59%). In the meta regression analysis, Colombian patients exhibited lower ESR levels, and were less likely to develop giant cell arteritis (GCA) as compared to the rest of LATAM data. CONCLUSION: Patients with PMR in LATAM exhibit similar phenotypes from other cohorts worldwide. Malignancy, GCA and latent PolyA should be considered in the routine clinical follow-up of patients with PMR.

RESUMO

Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic approach in the management of several pathologies, including central nervous system diseases. Previously, we demonstrated the therapeutic potential of human adipose-derived MSCs for neurological sequelae of oncological radiotherapy using the intranasal route as a non-invasive delivery method. However, a comprehensive investigation of the safety of intranasal MSC treatment should be performed before clinical applications. Here, we cultured human MSCs in compliance with quality control standards and administrated repeated doses of cells into the nostrils of juvenile immunodeficient mice, mimicking the design of a subsequent clinical trial. Short- and long-term effects of cell administration were evaluated by in vivo and ex vivo studies. No serious adverse events were reported on mouse welfare, behavioral performances, and blood plasma analysis. Magnetic resonance study and histological analysis did not reveal tumor formation or other abnormalities in the examined organs of mice receiving MSCs. Biodistribution study reveals a progressive disappearance of transplanted cells that was further supported by an absent expression of human GAPDH gene in the major organs of transplanted mice. Our data indicate that the intranasal application of MSCs is a safe, simple and non-invasive strategy and encourage its use in future clinical trials.

RESUMO

BACKGROUND: Little research on solitary drinking has focused on clinical samples. Previous research in college students has found that depression, suicidal ideation, and drinking to cope with negative affect are associated with drinking in solitary, but not social, contexts. These associations have not been examined among individuals with alcohol use disorder, despite their high rates of depression and suicidal behavior. METHOD: To fill this gap in knowledge, the associations of depression and suicidal ideation with solitary and social drinking were examined among 96 individuals seeking alcohol treatment, the majority of whom had alcohol use disorder (97.9%). Multiple mediation models were conducted to examine the mediating effects of two drinking to cope variables (drinking excessively to cope and coping motives) on the associations of depression and suicidal ideation with drinks per month and heavy episodic drinking in social and solitary contexts. RESULTS: Significant indirect effects were found for depression and suicidal ideation with solitary drinking variables through greater drinking excessively to cope. No significant indirect effects were found for social drinking variables. However, a positive direct association was found between suicidal ideation and greater social drinks per month that was not mediated by drinking to cope. CONCLUSIONS: These findings suggest that greater depression or suicidal ideation, through their effect on greater drinking to cope, are associated with greater solitary drinking in a treatment seeking sample. Drinking context should perhaps be considered in alcohol interventions, particularly when treating individuals suffering from depression or suicidal ideation.
